You're right -- it belongs in quirks. It might be a good idea to
add a line to the configure help for CONFIG_MTRR -- let people
know that if they have a 440FX chipset and they set CONFIG_MTTR
to yes that they also need to make sure passive release is enabled.

Definitely if there's a lot of quirks to take care of.
So far it looks like this is the first one besides the bridge
optimizations.

Works fine on 2.1.78. Not sure how many bios's have this problem.
I checked two SuperMicro motherboards (a P6SNE and a P6DNE with
AMI bios) and both of them failed to set the passive release
bit correctly.
