I have 2.1.82 too , but I think that cdu31a is working fine:

ztion:~# modprobe cdu31a cdu31a_port=0x1f88
ztion:~# mount -t iso9660 -o ro /dev/cdu31a /cdrom
ztion:~# cd /cdrom
ztion:/cdrom# ls          (NOTE: This is an OLD backup cd , which i had
nearby)

I had some troubles to get it working myself , but that was in 2.0. I
noticed that you have to specify the port , because the driver is not doing
any probing. It looks to me that you are loading it through kerneld , and I
dont know if it perhaps dont specify any port. 

Try to load it manually , and see if it works better.
