I don't believe that there is a whole lot of difference as far as NetBSD
is concerned.  Basically, it just helps determine which partition letter
will be assigned to the partition.  "Root&Usr" style partitions get
assigned to "a", then "d", and then "e", I think (although "b" might
actually fit in there as well).  "Usr" style partitions tend to get put at
"f", "g", and "h", I believe.  "Swap" style partitions are generally
assigned to "b".

Don't use "c"!  The "c" partition is the interface to the raw disk.  If
you managed to write to the "c" partition, you could overwrite the
partition map or the driver partition, yielding a totally scrogged drive.
Not a Good Thing ;-)  Use "g", that's your partition.

If you machine is panicing on that, you might consider changing SCSI
drivers, if possible.  Also, try mounting the drive again.  I've had one
of my disks cause a panic before, but it seems to be extremely
intermittant.

Who knows, it can't hurt to try ;-)

Later.
