Works fine for me, with the following nits:
cd0 at atapibus0 drive 1: <HP CD-Writer+ 7200, 4VO0798251132880021, V:003.0> type 5 cdrom removable
cd0: 32-bits data port

It's not locked. Wait about 45 seconds, and I'll bet you a dollar that you
get a note about lost DRQ on wdc0 or pciide0. The drive says above that
it supports DMA mode 1, but either it lies, or Manuel's DMA is broken. :)
If you try to do DMA to the other drive (any kind, HDs too) on the wdc bus
with this drive, you'll get a hang. I had to disable DMA modes on the wd1
that was on the same bus.

Now, I have a similar problem as of recent (<15 day old) kernels; something

error message from cdrecord.

the _cdrecord_ source? From pkgsrc, it works Fine for me (barring the
kernel changes above).
