[PATCH] don't suspend/resume 8xx chips

[Jesse Barnes <jesse.barnes@intel.com>]

Recent testing has turned up some bugs in the new Intel suspend/resume code 
for old, 8xx chipsets.  So for 2.6.25 it probably makes sense to apply this 
patch, which should prevent the new code from getting called on those 
chipsets.  We should have this fixed soon, but not in time for 2.6.25 
unfortunately.  Note that this patch (along with the suspend/resume code in 
general) could use more testing.
