First, the SU-Entry allows to partition the disk with it's real size
(2698061 512 byte blocks instead of 85*15*2112=2692800). I verified this 
with a second disk.
Here are the disktab entries for both disks, how the partitions are
and what I see on the console at boot time:

Note: partitions c,f and h of rz2 are bigger than those of rz0

Where do you expect the message about the disk type RZ58 or RZ58l ?
I think, what you see at boot time is just the disk's vendor string.
