In such cases I usually throw the firmware image at the IDA disassembler 
(we actually have bought two licenses) and look how it works. It shouldn't 
be a problem at all to locate the geometries table, and I would simply 
patch the firmware to work with the "new" drive.
For example, I have disassembled the firmware of the HP 7958A and found 
out how to low-level format a foreign ESDI disk (the original one had 
failed) with different geometry (the geometry is read from the drive since 
it is ESDI). In this case HP-UX mediainit in guru mode was my friend.
