Started experiencing the same. I run off an asus 900ha. I think the problem is related to your display settings and resolution. Try resetting to 800x600, reboot, check dmesg for a bit, then if it's clear, go up in resolution and repeat until you get it again.

I'm on a 1000H using 10.04 myself and get the same messages at boot and shutdown, adjusting the resolution to 800x600 doesn't help for me. I wouldn't want to work like that anyway, everything is stretched funny.

I got rid of it by changing a grub setting, link to article:

http://ubuntu-tutorials.com/2010/05/06/ubuntu-10-04-lucid-blank-screen-at-startup-workaround/

/etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash i915.modeset=0″
update-grub

I tried modeset=1 and it still did the same thing. modeset=0 makes the splash screen larger and as it is supposed to fade out or whatever kinda glitches for a split second. This was originally for not being able to see the screen at all on startup. This may not be the perfect fix, and I'm still gonna check out more options, but it's a start. The messages don't appear in dmesg anymore either.

This is another article I'm going to try in place of the earlier workaround, sounds promising -
