  This is exactly what I have (modulo the 'i'), on an i386 box:
cd0 at atapibus0 drive 1: <Memorex CRW-1622, AH1234567892123  L2, D4.0> type 5 cdrom removable

  So far, I've only played with it, but I was able to use
cdrecord to burn a short music segment and play it, and also
store a few MB's of files on it, and restore with no cksum
differences.  So it works, cdrecord's Linux-biased comments

  My only difficulty has been that my CDRW goes into PIO
mode rather than DMA mode, with two 20-second timeouts on the
initial cd0 device use, where it claims that DMA won't work due
to timeouts.  Manuel has been looking into it some, but we're
not sure yet whether it's due to my motherboard or the drive or
something else.  :)

  If you notice timeouts and /var/log/messages notes about
"downgrading to PIO", contact me (or Manuel) privately, and I
can fill you in on Manuel and my investigations so far.

  Good luck!
