Yes, it's a Mitsubishi.

Ok, I checked: it works fine under Mklinux. (must address as /dev/fd0H1440,
because fd0 is 'no such device'.  Also, X didn't work anymore, but these
maybe mk-newbe problems.)

On another unrelated note: while I was at it I tried to mount a
home-brew CD-ROM under Mklinux.  It failed gracefully, printing these
errors:

    <lev 2> block_read_reply: rdev 16:00 rsector 0x40 size 0x400 err=0x9c4=2500 "unknown error code" 
    isofs_read_super: bread failed, dev 16:00 iso_blknum 16 block 32 
    block_ioctl(dev=16:00, cmd=0x20001260) not implemented 

Trying to mount this particular CD-ROM under linuxppc-Q3's 2.2.6 or 2.3.23
freezes the kernel (not pingable, nothing in logs).
