Well, SCSI doesn't implement the BIG_GETGEO ioctl, so this isn't really much 
use.  You can use sector_div to do the divisions.

However, Andries Brower assures me that the geometry stuff is unused (at least 
from the cylinders point of view), so all of this is unnecessary anyway.  
There's a large thread about it on linux-scsi (don't have the reference).  The 
upshot was the code you can see in scsicam.c:scsicam_bios_param().

So the short answer is that this should be unnecessary.
