Alan,

I tagged piix as modular and removed the task file stuff.
The DVD and burner showedup. Running atapci, showed 
the drives as DMA enabled (I had to pick Generic PCI bus-master 
DMA support to get the piix option).
Hdparm would not work with piix loaded, I got similiar errors
when trying to mount (see below).

I could mount a cd and copy files no problem(without piix loaded). 
I then loaded the piix module. It loaded sucessfully. I tried to 
mount the cd  and got errors. 
Also /proc/ide/piix did not show up.

Log snips below, I also put links to full files at end of message.

If I missed something or you need anything else
let me know. Thanks!

Tony
