	While the "it wouldn't boot" is catastrophically imprecise, I
had what sounds like a similar problem about a month ago.
	I installed from the 9.0 CD and everything appeared to go
correctly.  However, on final re-boot the loader couldn't identify
the root partition.
	The solution was to identify the disks using the GPT labels in
fstab.
	Check the archive of questions@ for more details.
