Commit 7f74f8f28a2bd9db9404f7d364e2097a0c42cc12
(x86 quirk: Fix polarity for IRQ0 pin2 override on SB800 systems)
introduced a regression. It removed some SB600 specific code
to determine the revision ID without adapting a corresponding
revision ID check for SB600.
See this mail thread
http://marc.info/?l=linux-kernel&m=129980296006380&w=2
This patch adapts the corresponding check to cover all SB600
revisions.

Mea culpa!
A fix for a BIOS issue on some Lenovo systems introduced a regression
on another set of boxes (older HP Laptops) that have other BIOS
trouble.
Sorry for introducing this regression in .38.
Patch is on top of 2.6.38. Please apply.
Thanks,
Andreas
