CD-ROMs don't work on FreeBSD (I've mentioned this earlier, too). On
FreeBSD one only can read CDs in 2048 byte blocks. QEMU tries to read a
smaller blocks, at least when it tries to figure out whether the image
is a COW image.

I had some patches lying around, but they fixed the problem only
partially. CDs work with Bochs, however. So Bochs is aware of this
restriction.
