Then why don't you use getrawpartition(3)?

And we don't need to go this way, thats why we added getrawpartition(3)
to get the raw parition on different NetBSD archs.

Maybe, but only maybe have a fallback to /dev/cdrom if everything fails,

Because you 'normaly' only have one audio card and tv card in your system,
but it isn't unusal to have a cd rom, a cd writer or a dvd rom.
