Attached is a patch that does just that.

The default -cdrom still works, but you can also use -cdrom-a, -cdrom-b, 
-cdrom-c, and -cdrom-d to specify if the cdrom should be plugged in place over 
hda, hdb, hdc, or hdd respectively.

Also includes a few tests to make sure you don't clobber a hard disk with a 
cdrom, or use the same -hdX or -cdrom-X option multiple times.
