Alex found me a prep kernel. It seems to have issues with
its userspace, but; without this patch, when we probe the
IDE devices we get:

hdc: EQUMD DVR-MO, ATAPI cdrom or floppy?, assuming FLOPPY drive

(spot the byte-reversed halfwords!)

and with the patch we get:

hdc: QEMU DVD-ROM, ATAPI CD/DVD-ROM drive

so I'm pretty confident this patch is not just fixing a
test case but also fixing problems with real guests.
