Linux doesn't.  It IDE cdroms to IDE drive minor numbers, e.g.,

	hda = 1st controller, IDE drive
	hdb = 1st controller, IDE cdrom
	hdc = 2nd controller, IDE drive

The sequencing of controllers isn't unique, so the breakage doesn't
even work around the problem of mapping BIOS drive numbers to FreeBSD
device names except in simple cases.
