I also did tests on FreeBSD. On FreeBSD the system hangs immediately
when the burning process starts and UDMA33 is enabled. Of course
this isn't very nice. Downgrading transfer mode is more adequate.

Now I've acquired an Enmic with a Sil 0680 chip. With this controller
I can burn on FreeBSD using UDMA33.

It seems to me the Promise Ultra 100 TX2 only supports DMA on
CD-ROMs but not on CD-RWs.
