This list is just fine.

As a background to that image, we were one of the first groups to start
using Xen/ARM, and so had to build that ARM/Linux image to have a convenient
way to share effort with setting up development environments.  So although
it's not directly related to Mirage, we're happy to continue improving and
extending it on these lists.

This one's purely a Linux configuration issue.  You'll need to figure out
the right kernel modules to drive the GPU and add those to the xen-arm-builder
configuration process.  I would very much like to see this, but I think that
Magnus had a look a few months ago and ran into issues with GPU binary
blobs.  The situation may have improved since then, so any

Again, this one should be the standard Linux Cubie way of doing
that.  Magnus -- how did you get the LEDs to turn off on kernel
boot? (is it CONFIG_LEDS_TRIGGER or some userspace action?)

The latest Cubieboard images include the XenServer management
stack, so perhaps Dave can describe how to use the various XAPI
management tools to attach to the board.
