Okay, I just got a chance to try it, and the system got a little 
further. I already had the following enabled:

options	SMP
options	APIC_IO

options	SYSVSHM
options	SYSVSEM
options	SYSVMSG

I added the following:

options	SHMSEG=9

I took out the following:

options	HTT

Configured, compiled, installed, rebooted. This time, the system booted 
all of the way up. I got the message telling me my second processor was 
enabled and then got a login prompt. Definitely better. I logged in and 
ran top just to see what was happening. It appeared that processes were 
being assigned to both processors to run and everything went great... 
for about 20 seconds and then the machine froze again. Rebooted and got 
the same result. I'm now back on my GENERIC kernel and I'm good again - 
but with only one processor working.

I appreciate the ideas, and they definitely seemed to help, but I've 
still got something not quite right. I'm open to try other ideas or 
post any information that might be useful.

Thanks!
