Poul-Henning Kamp 24514292fa On PIIX4 based SMP systems use the PMTMR register for timecounting. ...

It is about 2.5 microseconds or roughly 3 times faster to use this
"PIIX" timecounter than the "i8254" timecounter.  Resolution is
also 3 times better.

The code cheats and don't register the PCI device, because other pieces
of code want to use it too.
