I seem to (vaguely) remember something related.
Could you check
* what hwclock says of cmos clock versus kernel one ?
* what other drivers (like ethernet cards) might be running ?
I would guess that what happens is that some driver is disabling
interrupts for long enough for the kernel to miss the click. It could be
caused by increased PCI congestion - in this case it would help if you
checked whether your video chip is on AGP bus or not. If not, try using
hdparm to simulate lots of pci traffic - does this cause the time to slip
as well ?
It could also be that your video card has an interrupt line that is
assigned (check in BIOS). If some other, possibly broken, driver is using
the same PCI interrupt you could get some unwanted interaction there..
Note: if you are not running DRI (don't remember whether there is for
S3Virge - probably not) it should be safe to "unassign" the
interrupt. Also it should be safe to assign it as well.. (though of course
hardware varies.. backup important things !)
