I'm still running 2.4 on this box, with a combi drive as the primary slave. That shows twice too, as
hdb: HL-DT-ST RW/DVD GCC-4320B, ATAPI CD/DVD-ROM drive
and then _many_ lines later is the second part
hdb: attached ide-scsi driver. scsi1: SCSI host adapter emulation for IDE ATAPI devices Vendor: HL-DT-ST Model: RW/DVD GCC-4320B Rev: 1.01 Type: CD-ROM ANSI SCSI revision: 02
So I guess all that's happening is that the two parts come together when we give up ide-scsi. The error messages look as if the kernel is trying to find any partitions, which isn't going to happen without media - you should see how many error messages I get from an ATPAI ZIP drive in 2.4 when I boot without media, but they're nothing to worry about.
HTH
