Dell Latitude C840 - if you use APM, you drop clock ticks. And that's
even *with* CONFIG_APM_ALLOW_INTS. I think I've caught the i8k driver
doing it as well - it seems to be a generic BIOS fuckage. Make a BIOS
call, drop some ticks. And unless somebody has a BIOS flash that works
better than Dell's C840A07, we're stuck with it....
