No, the GENERIC kernel is untouched by me.

The generic GENERIC kernel contains only:

options 	GEOM_PART_GPT		# GUID Partition Tables.
options 	GEOM_LABEL		# Provides labelization

I'll try the options/modules listed below

If you've followed this thread you'll probably remember me doing some 
experiments in VirtualBox at home last evening local time.

An untouched stable/8 GENERIC kernel had no problem mounting the root 
fs when told to do so by way of a UFS label, i.e. /dev/ufs/root. I 
tried VirtualBox' IDE controller and SCSI controller, and it worked 
flawlessly each time.
