IDE CDROM not detected

Description of problem:
I have IDE CDROM and SCSI CDRW. The xcdroast setup would not find
IDE CDROM, but finds SCSI CD-RW. It does not matter if CD-ROM will
have CD in it and if this CD is mounted or not. The older version of
xcdroast would not detect emty drive, but will find it if it has
a mounted CD in it.
Steps to Reproduce:
1.run xcdroast (I do it as root)
3.SCSI CD-R is there but not an IDE CDROM
This is a SuperMicro P6DGE motherboard (dual PIII / intel 440GX
chipset). SCSI is an add-on card -- Adaptec AHA-2940.
CDRW -- YAMAHA Model: CRW8824S
CD-ROM is /dev/hdb.
The new cdrecord uses scsi-commands to interact with the CD drives. Therefore
loading the ide-scsi module is mandatory.
Please try to unload the ide-cd and the ide-scsi module (you may need to stop
magicdev or autorun) and reload the ide-scsi module.
Does the ATAPI reader show up now ?
I do not use any desctop (Gnome or otherwise) just a windowmanager
(enlightenment). So I assume I do not have neither magic-dev nor
autorun running. I usually mount and unmount devices by hand.
I tried to load (insmod ide-scsi) and run xcdroast again.
Did not see any changes. here is lsmod output:

You really have to unload the ide-cd and the ide-scsi modules before you reload the ide-scsi module.
Otherwise you won't see any changes in xcdroast.
That worked. So, what should I do to make it work automagically?
Should I load ide-scsi before ide-cd (at boot time)?
You can add a line to your /etc/lilo.conf:
But you also have to change the link /dev/cdrom to point to /dev/scd0,
because you can't access hdb anymore when it is handled by ide-scsi.
Well, I figure it out myself quite some time ago. But when I tried to
play music CD using ide-scsi computer hanged dead (or may be X hanged dead -
it was a home computer and I could not try to telnet to it; neither
Ctrl-Alt-Backspace nor Ctrl-Alt-F1, etc are worked), but CD played fine :).
I am not picky, I can do loading modules by hand, so I did not persue
the issue further (but issue is there).
