The patch forwarded below still applies and compiles against
2.6.10-rc2-mm2 (I've edited it for a trivial context adjustment).
Please apply or comment on it.

Subject: [2.6 patch] cdrom.c: make several functions static
The patch below makes several functions in cdrom.c static.
This includes cdrom_is_mrw and cdrom_is_random_writable which were
EXPORT_SYMBOL'ed but weren't used anywhere outside of cdrom.h .
