To try zerwekh's suggestion:
Code:
su <type password; ->prompt changes to '#'>
dmesg | more
look for the device for your cdrom - but it very likely is sr0 with a 2.6.x kernel - might be /dev/hdc without SCSi emulation...
then try mounting "mount -r /dev/sr0 /mnt/cdrom" (still as root)

good luck...
