Subject: [15/44] x86, quirk: Fix SB600 revision check

2.6.32-longterm review patch.  If anyone has any objections, please let us know.

------------------

From: Andreas Herrmann <andreas.herrmann3@....com>

commit 1d3e09a304e6c4e004ca06356578b171e8735d3c upstream.

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.
