I don't know much about Qemu, but in regard to visualization in
general, I can tell that the -drive option will make *any* /dev/sd*
look like an ordinary disk to the guest OS.  So there shouldn't be any
particular interesting behavior regarding using a CF card, other than
if its speed is slow enough to cause problems.

If you want the CF card to appear to the guest OS as a CF card, you
will need to figure out "make a USB device visible to the guest OS".
