Thomas,

This all sounds great.  Are you working on getting the chrome9 DRM
bits into the kernel, or will you add the needed code to openchrome as
well?  I have been working with another user Bartosz that is trying to
learn the driver and we have found that DMA works a bit different than
we originally hacked in.  We have fixed the DMA initiliazation but are
debugging some other parts right now.
