The AMD chips are undergoing strict evaluation in -hardware since the K6-200 appears to have some serious problems. I'd go with the Intel just for safety. > System boots up to the console just fine; however, as soon as I start > X the system either hangs or reboots after a little bit.

Turns out the multi I/O chip kicks out a spare IRQ 7 whenever the serial port is closed. I had a quickcam installed at the time using that irq, so everytime the port closed it took a picture in space and scrambled the kernel stack, causing a panic. Disabling the qcam driver stopped the problem. > Any thoughts on this problem?

Have you tried hitting twice when the screen blacks out? It may be panicking but you can't see the output. The double return acknowledges the panic and forces a reboot.
