Nope, 2.6.21-rc1 vanilla does not work. 2.6.20 works. 2.6.20-gitX worked
until some acpi change broke it, the below patch fixed that for me. That
got merged in a later 2.6.20-gitY, but then some other patch broke it
again so that 2.6.21-rc1 is broken. Not much luck there :-)

So it looks like:

- c5a7156959e89b32260ad6072bbf5077bcdfbeee broke 2.6.20-git
- f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 should fix that.
- Something later than f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 broke it
  again.

Yeah, it gets trickier. I'll try
f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38 now and see if that works, then
bisect to 2.6.21-rc1 to find the other offender. I hope the other
offender didn't get added before
f3ccb06f3b8e0cf42b579db21f3ca7f17fcc3f38, we'll see :-)
