Ok... I'm back with a little update. I'm now able to mount raw
cdrom-devices using \Device\Cdrom<x>. I had some problems with my
DVD-drive at first, but when I turned off autoplay
(http://www.microsoft.com/windowsxp/expertzone/tips/february/knox1.asp),
everything goes smooth. I'm unable to mount if the drive is accessed by
explorer or any other program, and the drive is inaccessable from XP when
mounted in linux (no surprises here).

You claim it's possible to mount devices in a non-raw way using
\DosDevices\<drive letter>, but I've not been able to do this. If it's
then mounted through some windows-driver, shouldn't it be able to access
drives already mounted by XP in that way too (both harddisks and cdroms)?
