Many problems with wifi under 901 huh? But I can't still resolve my own.

After installing ubuntu-eee i got freezes during hitting Fn+F2. But wifi generally works fine.
I made safe and dist upgrade (via aptidute). No more freeze but the interface has disappeared!
There is no ra0 (or any other interesting interfaces on ifconfig output).

- wifi is on in BIOS
- lsmod shows rt2860sta loaded
- lspci: 01:00.0 Network controller: RaLink Unknown device 0781
- dmesg: nothing interesting found, but after hitting Fn+F2 i get:
[ 157.481097]
[ 157.481103]
[ 157.481104] === pAd = f9094000, size = 580808 ===
[ 157.481107]
[ 157.481130] <-- RTMPAllocAdapterBlock, Status=0

old scripts from /etc/acpi removed

any ideas?
do you need any additional informations?
