asynchronous counter problem.
Basically it figures out a mask and then the timer code loops until two
masked reads yield the same value, guarenteeing that we haven't caught
the timer during a carry.

:I have some reservations about this, because I'm not sure that 10
:successive reads will catch the ripple-counter problem that the old PIIX4s
:have.
Just goes to show that I need to document my code :-)
Those reads are not detecting the ripple-counter problem, they are
figuring
