It works in 2.6.1, but is still broken in -mm1.  The only other 
differences between the kernels was whatever make oldconfig did to 
switch to 2.6.1 and that I'm running hostap-cvs on -mm1 (although I 
can't imagine how that would be a problem).

Config for -mm1 is attached.

I'm guessing it's the AIO stuff -- I'll try -mm2 later today.
