DMA disabled by default for optical drives - why?

[Jason Smith]

After I have installed Ubuntu 5.10 I din't manage to write not even one
DVD, because DMA was not enabled. Not to mention
the high CPU usage when I was accessing my optical drive.

Luckily Nero warned me about the DMA misconfiguration, I corected the
problem
and now everything works fine. I think DMA should be enabled by default.
