If the OP did create an own rotten kernel this will not help.

ide-scsi seems to be buggy and unmaintained in newer Linux releases.

cdrecord -scanbus on a _vanilla_ Linux kernel will work as well as 

just calling "cdrecord ..." _without_ dev= parameter 

Most users have only one drive and in this case, cdrecord will automagically 
search for the right device.

This is how the typical output from a cdrecord -scanbus call looks on a
vanilla 2.6.13 Linux kernel:

cdrecord -scanbus

As you see, there is no need to hand craft e linux kernel - cdrecord works
around the oddities in the Linux device addressing ;-)
