This line alone is enough to tell that the kernel is accessing the DVD
drive (which is a PATA drive on a SATA port via a SATA-PATA-bridge)
using BIOS IDE emulation. DMA is impossible in this scenario.

Yes. Native support for SATA ATAPI devices is disabled in 2.6.11 and
2.6.12. It will be enabled in 2.6.13 by default. You can enable it in
2.6.11/12 and recompile your kernel, but I wouldn't suggest it. There
are some bugs that are only fixed in 2.6.13.
