Also google for BIOS Updates. They might fix the problem. ;-)

The first time I saw such a problem was two years ago iirc. I then saw
them now and then on different ati / uli(ali) hardware with diffenrent
kernels (not fedora specific). Never elsewhere.

iirc it can be worked around without acpi. Or maybe try this kernel
parameter (I tried it but can't remember if it helped):

        clock=          [BUGS=IA-32, HW] gettimeofday timesource override.
                        Forces specified timesource (if avaliable) to be used
                        when calculating gettimeofday(). If specicified timesource
                        is not avalible, it defaults to PIT.
                        Format: { pit | tsc | cyclone | pmtmr }
