The IXP425 does not have a match register, AFAICT. It does have four 32-bit counters clocked at 66.66 MHz: a watch dog, a free-running timestamp, and two general purpose timers. The general purpose timers may be used either as one-shot timers (count down to zero and stop) or as periodic times (count down, automatically reload, and keep going). I already have xenomai running on the IXP425, but I will have to take a closer look at the timer code.
