There are indeed a gazillion or so clock options you can
specify on the kernel command line. Perhaps making it
use a different clock source would work better. (The kernel
may believe it knows something about the clock it picked
which isn't actually true on the motherboard in question).

rpm:

        clock=          [BUGS=X86-32, HW] gettimeofday clocksource override.
                        [Deprecated]
                        Forces specified clocksource (if available) to be used
                        when calculating gettimeofday(). If specified
                        clocksource is not available, it defaults to PIT.
                        Format: { pit | tsc | cyclone | pmtmr }

        clocksource=    [GENERIC_TIME] Override the default clocksource
                        Format: <string>
                        Override the default clocksource and use the clocksource
                        with the name specified.
                        Some clocksource names to choose from, depending on
                        the platform:
                        [all] jiffies (this is the base, fallback clocksource)
                        [ACPI] acpi_pm
                        [ARM] imx_timer1,OSTS,netx_timer,mpu_timer2,
                                pxa_timer,timer3,32k_counter,timer0_1
                        [AVR32] avr32
                        [X86-32] pit,hpet,tsc,vmi-timer;
                                scx200_hrt on Geode; cyclone on IBM x440

                        [S390] tod
                        [SH] SuperH
                        [SPARC64] tick
