Ralink wireless card not working out of the box

[Ukebane]

Edit: Problem solved, solution:

GRUB_CMDLINE_LINUX="acpi=force irqpoll"

After installing Ubuntu 9.10 today I couldn't get my wireless card to work, I tried several things noted in other threads, but to no avail.

lspci -v | less gives me the following:

00:06.0 Network controller: RaLink RT2561/RT61 802.11g PCI
        Subsystem: RaLink Device 2561
        Flags: bus master, slow devsel, latency 64
        Memory at ffff8000 (32-bit, non-prefetchable) [size=32K]
        Capabilities: <access denied>
        Kernel driver in use: rt61pci
        Kernel modules: rt61pci

ndiswrapper -l gives no result

iwconfig shows me the following:
