Current wine is using /dev/sgX to access CD-ROM devices. Since

Add ACL to device nodes that already get GROUP="cdrom".
sg is kind of deprecated and should really not be used anymore by
anything. Ideally we would start no even loading the module.
Who exactly depends on it and can not be fixed? Why does Fedora and
SUSE does not seem to have any problem the last couple of years?

Other distribs are also having problem with this :
gentoo : http://bugs.gentoo.org/321007
fedora 13 : http://bugs.winehq.org/show_bug.cgi?id=23313
Wine's code is using /dev/sgX, I don't know if there're some patches
around to change this.
It seems an usual fix is to add oneself to the cdrom group, but this is
hardly an out of the box solution for a non technical user that would
just install his linux distro of choice.
The fact that this problem is often related to users wanting to run
protected games under Wine is certainly another reason why it didn't get
much attention or fixes so far (in my case I want to access low level
scsi functions with EAC).
Using acl in udev would provide a solution that automatically enables
access to /dev/sgX for any logged user, without having to change /etc/group.
