That's pretty consumer grade - just like what i have (k8vdeluxe, 3200, 1G ram, 
sata on the promise controller).

Don't run that, it'll just tell you that the system is only marginally faster 
than the athlon XP it replaces.

sk ethernet was a problem in early snapshots - I started with one of David's 
snapshots from early november, dropped in an xl card (3c509) , cvsupped to 
- -CURRENT, built that, and all was fine.

Serial console is always a good idea. Expesially when things crash under X.

SMP is mandatory in -CURRENT and doesn't affect UP systems.

The power-saving stuff in the BIOS can be very tricky. I had endless lockups 
when C&Q was turned on - nice and quiet, but max. uptime of about 12 hours. 
Since I've switched that off again and just let the CPU cooler run at max 
speed all the time and don't fiddle with memory timings or voltages, it runs 
much better.

Not spectacular, but hey. It means it was 14 days ago that I last accessed the 
cdrom, which is a sure-fire way to panic the system.

The users that I support would double-click on a landmine to see what it did.
