UDMA settings won't help you when you burn the CD in DAO mode. The
problem is the kernel. It disables DMA when a program uses
non-standard block sizes for data transfers - this happens when burning
CDs in RAW mode, eg. DAO/SAO, audio CD grabbing, etc.
There is a patch to enable DMA functionality in this case. However,
though it seems to work best with my (VIA-IDE) systems, it seems to
trigger some random bugs with other software/hardware combinations.
