	Attempting to use a Belkin USB CompactFlash reader results in the
	system crashing. It appears that the umass driver is incorrectly
	reporting the CF card geometry. I have had no problems using the 
	CF card on an HP Jornada (hpcarm port). I am having to use FreeBSD
	to read the CF card, and it works perfectly.
	Boot up the machine with a CF card in the reader. The kernel will
	Example when using a 64MB CF card:
	umass0 at uhub0 port 1 configuration 1 interface 0
	umass0: SCM Microsystems Inc. eUSB CompactFlash Adapter, rev 1.10/2.18, addr 2
	scsibus0 at umass0: 2 targets, 1 lun per target
	uhub0: port error, restarting port 2
	uhub0: port error, giving up port 2
	scsibus0: waiting 2 seconds for devices to settle.
