I've got a NEC 4X atapi drive and it works quite well under the 2.2 SNAP
release, to
be honest I haven't tried it with 2.1.5.  

In your kernel config file, make sure you've disabled wd1 ( second hard
disk, first
IDE controller ) or it will fight with the wcd0 driver for control of
the CDROM:

# comment me out!
# disk            wd1     at wdc0 drive 1 


Hope this helps,
