Try:

mount -t iso9660 /dev/cdrom /mnt/cdrom

Just because it appears ext2 doesn't mean it is ext2.

I've seen some that claimed to do so. The only 2 I tried didn't work.
Sorry I can't recall the names of any because it's been some time since
I tried them. I know you can find them on freshmeat.

Just be careful. I found out through my logs that freshmeat is in bed
with doubleclick and THEY love gathering as much nosey information on
everybody that they can for the purposes of selling it. I personally
have stopped going there and have looked into other avenues.
Unfortunate, yes. But I make no exceptions.

Try tomsbrt, ramlinux, zdisk and a whole host of others, also available
on freshmeat (and appwatch, and linuxberg and many others, most of whom
don't sell their souls to doubleclick).
