With kernel 2.4.27, I was able to have Debian recognise my two burners (one is an Optowrite DVD-RW/CD-RW, the other a Samsung CD-RW). With 2.6.8 however, they work as ordinary CD/DVD devices, but cdrecord does not recognise them, and k3b does not present them as device options.
The error message "cdrecord -scanbus" generates is as follows:
Code:
cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.
cdrecord: For possible targets try 'cdrecord -scanbus'.
cdrecord: For possible transport specifiers try 'cdrecord dev=help'.
cdrecord:
cdrecord: For more information, install the cdrtools-doc
cdrecord: package and read /usr/share/doc/cdrecord/README.ATAPI.setup .
This extract from the startup routine might be of some use:

Note: I have to have ACPI turned off, otherwise the kernel does not load (crashes at ATA device detection). Note also that the only IDE devices in the machine are the burners - the hard drive is a SATA device (recognised as sda - the DVD burner is hda and CD burner hdb, it seems).
An entirely unrelated, but bizarre issue with k3b, when it starts up: it reports it cannot find dvd+rw-format installed, yet it is and with the correct permissions set.
Help with either issue would be most welcome.
[Sarge] Debian does not recognise CD-ROM devices as burners under 2.6.8
