For some reason with my cd-rw, I'm getting spurious "CDROMPLAYMSF: No
medium found" messages when trying to play cds while using ide-scsi
emulation. With the ide-cd module used instead, it works fine. I haven't
tested this with any kernel versions other than 2.4.19-pre[45] (I only
recently got the cd-rw).

I got the following output when playing around with workbone:
play(150,127199) stopped #1
msf = 0:2:0 28:15:74
CDROMPLAYMSF: No medium found
play(150,127199) stopped #1
msf = 0:2:0 28:15:74
CDROMPLAYMSF: No medium found
play(150,127199) stopped #1
msf = 0:2:0 28:15:74
CDROMPLAYMSF: No medium found
playing #1 00:03 00:05

The cd-rw is reported on module loading as follows:

hdd: ATAPI 40X CD-ROM CD-R/RW drive, 2048kB Cache, DMA

Attached scsi CD-ROM sr0 at scsi0, channel 0, id 0, lun 0

I'm using the following patches:

various bttv from http://bytesex.org/patches/

And the following 3rd party modules:

Just in case it's important, my motherboard is an abit bx6r2, which uses
the intel 440BX chipset. The ide chipset is listed in lspci as the
82371AB PIIX4 IDE.
