Modified Files:
	src/sys/dev/pci: files.pci piixpm.c

Log Message:
-make sure it is a PIIX4 before accessing counter stuff
 (there might be usable registers on 440mx and that ATI thing too,
  but that needs to be checked/tested)
-make sure the I/O access to the power management stuff was enabled
 by the BIOS before trying to map/access stuff
-most PIIX4s have a bug in the timer latch which causes jitter or worse
 if it is read naively - check the revision
-use common code in dev/ic/acpipmtimer.c
