There is not a lot needed to help get this in debian.

1) The responses should go to the arm-netbook mailing list and not to my
email address only.
2) Be patient. This driver is in early stages, and there is a quick X11
session input but it does not have a proper X11 driver. A proper driver
includes DRM, KMS, Framebuffer, Mesa Drivers and a DRI2 based X11 driver.
3) This does not currently include OpenGL nor OpenMAX  support. Both of
these features are required for useful integration on XBMC, Flash and other
4) As for actual integration, I would say that all it really needs is
proper packaging scripts to be added. Currently I know this driver depends
on X11, and libVPAU.
