We still use the 8254 to generate timer interrupts for the
systimer API.
A great project, if you want one, would be to use the APIC on cpu #0
(not ACPI)... the actual APIC timer, which can also generate interrupts,
instead of the 8254. So if the APIC is present, we'd use that.
I do not think it would be very hard to do, and that combined with
using the acpi timer for our real-time timebase would allow us to
avoid the use of the 8254 entirely.
