Ultra-5 with 333MHz cpu module, (currently not) booting on serial console. 
I have a keyboard and mouse, but they are currently resting in the closet
nearby.  The kernel config is GENERIC with features I don't have hacked out;
nothing esoteric at all.  I do usually remove and _ROOT options 

I'll snag the latest snapshot and try that.
