Subject: workaround for buggy BIOSes and i845 chipsets

Hello,
Vojtech Pavlik helped me to workaround this issue. This patch is backport
from 2.5 to 2.4 and is applicable into 2.4.19-rc3. Maybe somebody will need
it too. It works correctly on my system.

That only clears the buffered kernel records.
2.4.19-rc3-ac2 has the proper and correct fix to deal with XP BIOS HBA

Cheers,
