Well, as I showed in my original message, I was able to mount the CD as
a cd9660 file system, so it appears to work.

Well, /var/run/dmesg.boot says:

acd0: setting PIO4 on ICH3 chip
acd0: setting UDMA33 on ICH3 chip
acd0: <HL-DT-STCD-RW/DVD-ROM GCC-4241N/A100> CDRW drive at ata0 as slave
acd0: read 4134KB/s (4134KB/s) write 4134KB/s (4134KB/s), 2048KB buffer, UDMA33
acd0: Reads: CDR, CDRW, CDDA stream, DVDROM, DVDR, packet
acd0: Writes: CDR, CDRW, test write, burnproof
acd0: Audio: play, 256 volume levels
acd0: Mechanism: ejectable tray, unlocked
acd0: Medium: no/blank disc

And atacontrol says:

ATA channel 0:
    Master:  ad0 <HTS548040M9AT00/MG2OA50A> ATA/ATAPI revision 6
    Slave:  acd0 <HL-DT-STCD-RW/DVD-ROM GCC-4241N/A100> ATA/ATAPI
revision 5
ATA channel 1:
    Master:      no device present
    Slave:       no device present

(Why the laptop was set up so that both devices are on the same channel,
I doubt I'll ever know.)

OK; well, I s'pose it's some small comfort to be aware that I'm not the
only one seeing the apparent issue....  :-}

I could boot from a different slice, and exercise 7-CURRENT (from
yesterday -- I didn't have time to build today's -CURRENT yet), if that
might help.
