Actually, this does not seem to worry some Unix vendors... I was
running Interactive unix on my home machine (dumped it because slip
was hopelessly broken).  They had a driver for the vga card - you
could use an ioctl to set and read the registers of the VGA card.  I
actually ported the R5 clock probe program to use these ioctls -
seemed to work ok though the numbers where a bit dodgy due to the
scheduler.
