No. I tried to install from the final release alternate Kubuntu 8.10 CD and got hit by the problem. To install, I had to manually used pci=nomsi (using F6 to edit the kernel parameters).
Also, I recently (on 2008-11-21) updated the system and tried removing the pci=nomsi workaround from menu.lst. Didn't work, so the workaround is still needed.
I don't know why your Sata DVD drive now works, but for me the problem has remained the same until now.
I have no idea whether this but affects Sata DVD drivers differently from Sata HD drives, or if your bug was a different one.
