I'm a bit confused about the policy here: if we look at the Intel chipset 
overrides for HPET, they conditionally enable the HPET _without_ the 
hpet=force option if you have a chipset on the whitelist.

If Intel can do this on their chipsets, why is this not being done for the ATI 
chipsets for which (presumably) AMD have specs?

One thing I'd considered was that HPET isn't actually used very often on Intel 
chipsets because on most recent Intel CPUs the TSC is stable, but I think 
either the Intel quirk should be consistent with the hpet=force usage, 
or "known correct" HPET overrides should just always be applied.
