This patch makes seabios use the acpi pmtimer instead of tsc for timekeeping. The pmtimer has a fixed frequency and doesn't need calibration, thus it doesn't suffer from calibration errors due to a loaded host machine.
The patch looks okay to me, but is it still needed? (I recall seeing something on the kvm list about a bug fix to the main timer.)
Timing will always be fragile in a vm, so I think this can make things more robust.
