> When I upgraded from kernel 2.6.22.6 to kernel 2.6.30-gentoo-r8 I found out that I could no longer use Kismet with my zd1211 based USB wifi device. I even changed the "/usr/src/linux" link to point to the new source and recompiling Kismet.

Be sure you're running the latest kismet (2010-01). You completely changed everything about your drivers, and the since the older kismet releases predate your kernel they don't handle it very gracefully.

I'd also suggest going to 2.6.32 or at least installing the compat-wireless backports, because I recall .30 having a lot of wireless problems in general.
