Well, hdparm does work for CD drives (hdparm -E), but not for CD/DVD combo drives...
And also, the tools I was thinking of isn't called setspeed...it's called setcd, and it uses ioctl(fd, CDROM_SELECT_SPEED, speed) which doesn't work on DVD players apparently. The same goes for the other tools I've tested ("hdparm -E" and "eject -x").

Which also uses the above mentioned ioctl...
