kernel built from cvs update to D2009.12.05.05.00.00 boots & works
fine. kernels from cvs updates after the dev/ata commit on 12/6 can
not mount my ufs partitions in either legacy or w/ options ATA_CAM

here is verbose dmesg from kernel built w/ sources updated to 12/5/2009 at
midnight EST:  http://xiombarg.uffner.com/dmesg_20091205.txt

as soon as i can set up another PC & serial console i'll get you a verbose
boot from new kernel.
