This test uses the scsi_debug module to test mkfs against
various physical & logical sector sizes, and with aligned
and unaligned devices.

Dave, I think this implements all your suggestions (in one way or
another...) except the non-modular scsi_debug. I don't know
how to manipulate things like offset if it's built in, but
if you want to look... I don't see it.
