Quick summary:
I had a working 10.04 installation, and I decided to upgrade to 10.10 (via the command line, I tend to not use this box as a desktop, though it isn't a Server install or anything). Rebooted, and it showed an error of the sort "udevd-work[xxx]: opening directory /dev/null failed: no such file or directory", and then it went to black. Pinging the box suggested that it wasn't doing anything but sitting there, half-dead.
I booted from a 10.04 LiveCD I had handy, and tried to debug, checking the boot settings. Here's the output of Boot Info Script:

And now I'm left with no further ideas. I made a 10.10 LiveCD, too, and tried to use that, with no luck—the same black screen.
Edit: Just noticed that the date on the Boot Info Script is horribly wrong; didn't bother to correct the time settings in the LiveCD instance.
I had a working 10.04 installation, and I decided to upgrade to 10.10 (via the command line, I tend to not use this box as a desktop, though it isn't a Server install or anything). Rebooted, and it showed an error of the sort "udevd-work[xxx]: opening directory /dev/null failed: no such file or directory", and then it went to black.

## lines between the AUTOMAGIC KERNELS LIST markers will be modified

## DO NOT UNCOMMENT THEM, Just edit them to your needs
## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=1e71625b-3729-404e-a872-be52f74f464f ro
## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,0)
## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true
## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false
## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=quiet splash noapic
## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false
## Xen hypervisor options to use with the default Xen boot option
# xenhopt=
## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0
## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(recovery) single
# altoptions=(recovery mode) single
## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all
## specify if running in Xen domU or have grub detect automatically
## update-grub will ignore non-xen kernels when running in domU and vice versa
## e.g. indomU=detect
## indomU=true
## indomU=false
# indomU=detect
## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true
## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false
## should update-grub add savedefault to the default options
## can be true or false
# savedefault=false
## ## End Default Options ##

And now I'm left with no further ideas. I made a 10.10 LiveCD, too, and tried to use that, with no luck—the same black screen.
Edit: Just noticed that the date on the Boot Info Script is horribly wrong; didn't bother to correct the time settings in the LiveCD instance.
