i have the same problem. 2.6.29 was fine, 2.6.30-rc1 doesn't work. i
tried applying the above mentioned patch but it didn't make any
difference. at any rate, i have iwl3945 compiled in the kernel and not
as a module and i don't use wep. this is the relevant part from syslog:

looking through the logs i also noticed this:
