Thinkpad T60 with Atheros working only after restart from Windows

Hi,

Would you be willing to try a -HEAD snapshot on your laptop?

Maybe I've fixed it as part of the other driver work that I've done as
part of development in -HEAD.

But right now I really have no idea. I don't have a T60 here that has
that chip in it. If all the T60 BIOSes allow AR5418 NICs then I can
try it out, but all of the T60's I've played with thus far have the
intel hardware in it.



Adrian
