>Description:
The amdtemp(4) device was recently modularized.  However, using it as
a module is really not very useful, since by default a "pchb*" device will
attach to the same "pci? dev ? function ?", precluding subsequent attach
of the amdtemp device.  (When this code is built-in to the kernel, the
amdtemp(4) match() returns a higher value than pchb(4).)

It was suggested in private Email (I forget who it was) that the amdtemp(4)
should really attach at pchb?, since there is at least one other device
(agp-related?) that shares the same pchb on certain processor models.
