OK, thanks. Note to Greg: CONFIG_PCI_MULTITHREAD_PROBE+ipw2200 = oops.

Another reporter mentioned that he could only get his wireless to associate

ipw2200 works OK for me, fwiw.

There's a largeish ipw2200 update in mainline now. That'd be worth testing.

It looks like that ipw2200 update was in 2.6.18-mm1 though. Did that work?
