no such module (that tells me something).

yes.
    hdd: UJDA310 ATAPI CD/DVD-rom drive

am running 2.6.5-1.

sorry to have troubled you folk, but your answers were
helpful.  in the end the answer was to RTFM, which of
course i had done, though not carefully enough.  i had to
add ATA: before the scsi address, and to try
    cdrecord -scanbus
to find the correct address, which was 1,1,0, not
0,0,0 as it had been under rh9.0.  the addition to the
kernal command line was indeed unnecessary.  all is well.

again, thanks all.
