I can't use my CD-rom as a device-mapper target, is this intended?

"0 2048 linear /dev/hda1 0" works, "0 2048 linear /dev/hdc 0" does not.

(I'm actually trying to do encrypted CD-roms, but it's reproducable
using linear mappings as well.)

Right now I have to use a loopback device on the CD, then I can use
it as a device-mapper target.
