qemu-devel port: please test -cdrom patch with non-FreeBSD guests

[Juergen Lock]

Hi!

 I would like to commit the patch below to the qemu-devel port that
chases recent FreeBSD atapi-cd.c commits (it fixes recent FreeBSD
guests no longer seeing a disc in the emulated cd drive) and I want to
make sure it doesn't introduce regressions, so I'd be grateful if you all
could test it with as many (especially non-FreeBSD) guests as possible,
using the emulated cd/dvd drive. (like, pass an iso as -cdrom and
try to access it from the guest, play with `eject cdrom' and
`change cdrom another.iso' monitor commands, etc.  Btw, at least Windows
guests also needed an expicit click on `eject' in the guest in order to
notice disc changes, so if thats still the case its at least not new.)

 Thanx,
	Juergen
