Can't you put the connector on the Breakout-VX? :(

After loading the pxafb module, do this:

dd if=/dev/urandom of=/dev/fb0 bs=272 count=960

That will fill the framebuffer with "noise" so you should see colored
speckles on the screen.

The screen we're settling on looks like it's 99% going to be the
Samsung equivalent of the Sharp screen, which merges the Sharp's 3
ribbon cables (signal, power, and touchscreen) into a single ribbon,
but the screen is otherwise basically identical.  It looks like LG
has an exact cross for this Samsung part too.  We'll be revising the
console-vx to add this connector (and all the required voltage-
shifting logic), as well as creating a new audiostix-vx (which
doubles as gpsstix-vx) which has the connector, as well as putting
the connector on the upcoming GPRSstix.  ETA on this boards varies,
but basically they're all "this summer"
