Ingo,

reverting the commit 5d423, titled "x86/pci: remove rounding quirk
from e820_setup_gap()" fixes loading of ath9k on an Acer Extensa
7630EZ. We've troubleshooted the issue with the user,  Bernhard, who
eventually did a full bisect between 2.6.30 and 2.6.31 and found 5d423
was the culprit. For details please feel free to check:

http://bugzilla.kernel.org/show_bug.cgi?id=14402

Can you please consider reviewing this issue and help determine if
this indeed needs to be reverted for 2.6.32 and the next 2.6.31.y.

I am curious if other devices would work by reverting this as well.

  Luis
