Would you know by chance the most recent kernel where this wasn't an issue? I'll also see if the Intel contacts I have see this with any of their Alpha5 testing they just began. Thanks.

same problem here with ibex rc and an intel pro wireless 3945abg on a fujitsu lifebook. 2.6.26-5-generic on the alpha 4 cd was my last known working kernel (ended up booting in to the alpha 4 live cd and downloading/installing the older kernel packages).
