If it doesn't work under your old kernel, it's probably a buggered cdrom I'm
afraid.

As you thought, discount the /sbin/mount thingy. The error message is coming
from the kernel, quite why I thought to ask you to strace is beyond me now
:/. ho hum :) 

Your error message comes from one specfic place, linux/drivers/cdrom/cdrom.c.
Go into that file, and find the line that says:
	#define ERRLOGMASK (CD_WARNING)
Either comment it out and use one of the all-encompassers below it, or
change it to:
	#define ERRLOGMASK (CD_WARNING|CD_OPEN)
Recompile, reboot, etc. Try mounting again. Your log should be full of
interesting messages, most of which will probably begin with "bummer" I
imagine.

Cheers,

Alex.
