I'm sorry, I misread that completely. The reason for the extra quirk on 
the HPs was down to their DSDT setting thermal trip points incorrectly 
if the override weren't ignored - it would trigger at boot time, not 
after suspend/resume. In theory I think that should be handled by the 
chipset-specific quirk code already, with the DMI list as a backup. It 
may be that we need to look at the chipset quirk code?
