I'm seeing the exact same problem on, guess what...

FreeBSD 5.0-CURRENT #162: Sat Mar 23 19:49:09 CET 2002
    des@des.thinksec.com:/usr/src/sys/i386/compile/DES
Preloaded elf kernel "/boot/kernel/kernel" at 0xc041c000.
Timecounter "i8254"  frequency 1193182 Hz
Timecounter "TSC"  frequency 350796334 Hz
CPU: AMD-K6(tm) 3D processor (350.80-MHz 586-class CPU)
  Origin = "AuthenticAMD"  Id = 0x58c  Stepping = 12
  Features=0x8021bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,PGE,MMX>
  AMD Features=0x80000800<SYSCALL,3DNow!>
real memory  = 671072256 (655344K bytes)
avail memory = 647180288 (632012K bytes)
K6-family MTRR support enabled (2 registers)
Using $PIR table, 8 entries at 0xc00f0d00
acpi0: <ASUS   P5A     > on motherboard
acpi0: power button is handled as a fixed feature programming model.
acpi_cpu0: <CPU> on acpi0
acpi_pcib0: <Host-PCI bridge> port 0xcf8-0xcff on acpi0

IOW identical CPU, nearly identical board.  I worked around it by
disabling the ACPI timer by adding this to /boot/loader.conf:

debug.acpi.disable="timer"
