I have the following:

CPU: AMD-K6(tm) 3D processor (300.68-MHz 586-class CPU)
  Origin = "AuthenticAMD"  Id = 0x580  Stepping=0
  Features=0x8001bf<FPU,VME,DE,PSE,TSC,MSR,MCE,CX8,MMX>
real memory  = 67108864 (65536K bytes)
avail memory = 62124032 (60668K bytes)
...
chip0: <VIA 82C597 (Apollo VP3) system controller> rev 0x04 on pci0.0.0
chip1: <VIA 82C598MVP (Apollo MVP3) PCI-PCI bridge> rev 0x00 on pci0.1.0
chip2: <VIA 82C586 PCI-ISA bridge> rev 0x41 on pci0.7.0
ide_pci0: <VIA 82C586x (Apollo) Bus-master IDE controller> rev 0x06 on pci0.7.1
chip3: <VIA 82C586B ACPI interface> rev 0x10 on pci0.7.3

and I have never had a reboot.  I have hit the limit of my swap when running
too many things (especially X, Netscape, the Gimp, and AOL's TiK, which has a
memory leak) and watched X curl up and die because it got killed due to the
lack of swap, but that is normal behavior, as the alternative is to lock up.  I
also have the following CPU-specific options in my kernel:

# CPU options
options         "NO_F00F_HACK"          #not a iPentium
options         CPU_WT_ALLOC            #enable write-back allocation
options         NO_MEMORY_HOLE

It probably won't make a difference, but it might.  If it does, then that would
help narrow down the bug.
