Might really want to forward this onto the linux-sparc list, Probably get an answer that fits your hardware. But,.. some Ques. & maybe a hint below.

Martin, Do an 'ls -l ?cd* | more' and see if there are some devices like :
scd5:0 ^- Some form of delimiter, Maybe even no delimter. Or, scd5a b c d e f
Then again the Driver/Kernel/Device combination may not be handling Multi-lun CD's correctly. ;-}
In my HOWTO's & what not, there is -only- the mention that hard-disk-drives on bridge boards get assigned to the next device letter IE: disk ID0,Lun0 ; disk ID0,Lun1 w/b /dev/sda ; /dev/sdb, But how the kernel et-al, handles the cd-rom cases doesn't seem to be available in my literarture.
