You could also try pdisk. It's not a normal MacOS app... it has a 
CLI, and it allows you do edit the partition map of any disk 
(including the boot disk). Unfortunately, it doesn't format disks, 
but you could use it to change the label/type of the FWB driver 
partition (or whatever it is) to something else... or delete it's 
entry entirely.

You can get it from Bob's server:
ftp://murphy.dyndns.org/pub/map/

You can also resize partitions with pdisk (because it doesn't format 
them), but you have to be clever. (And use a disk repair utility 
liberally.) IIRC, I did it to an HFS partition once, but I'm really 
not sure I if I just thought about it or actually did it.

HTH,
