Dual cd drives

[George E Sollish <gsollish%autogear.net@localhost>]

Hi,

I have recently acquired an IBM Intellistation Z Pro, now running 5.0. 
The box has two 'cd' devices, an IBM DVDRAM drive and an IBM CD-ROM drive, 
the problem being that only the CD-ROM is reliably found on boot, although 
both are invariably found by the BIOS.

I'm posting a diff from two boots of the same 5.0_STABLE kernel taken on 
the same hardware about half-an-hour apart:

Any ideas how to fix this?

Thanks.
