Two people (Patrick and Matthew) are reporting this post-2.6.28
regression.

Could someone please recategorise the report to something more
appropriate than drivers_other?

Thanks.

Can you try disabling pciehp? eeepc-laptop provides the same 
functionality. If that works, I have a patch here somewhere...

I realized you were talking to Patrick, but I just wanted to say I do not
have pciehp compiled in. Here is my 2.6.29-rc7 kernel config:

one got deleted)

Cheers!

[Matthew Garrett]

Ok. There haven't been any changes in eeepc-laptop that I can see 
causing this, and nothing springs to mind as an obvious cause. I know 
it's a pile of work (especially on an eee), but is there any chance to 
can bisect this to a smaller range of patches?

[pyther]

I can do that, however how would I go about narrowing it down to a smaller
range of patches? Would I simply apply patches from
(http://kernel.org/diff/diffview.cgi?file=%2Fpub%2Flinux%2Fkernel%2Fv2.6%2Ftesting%2Fpatch-2.6.29-rc7.bz2)
to the 2.6.28 source and compile until I find the one that breaks the hot
key functionality?

If you have a git checkout, 
http://www.kernel.org/doc/local/git-quick.html#bisect has good 
instructions on how to do a bisection.
