[Arm-netbook] microSD breakout board, suitable for debugging using tablets.

Tried getting ubuntu running too. Here is my setup:
- the external sd contains an ubuntu. I used the build that was made for 
the Eee Transformer
- bootfs contains a small android init setup, that starts adbd, mounts 
the external sd, chroots inside it, and starts ubuntu's init (modified 
it a bit, so it won't complain about running in a chroot)

Xorg doesn't work for me either, I get a restart if I try to use it, 
without anything useful inside /proc/kmsg. The framebuffer does work 
however as for you, I can cat /dev/random to it and get all kinds of 
junk on the screen. fbset also works, here is the output of it, it might 
be useful:

root at localhost:/etc/X11# fbset -i

mode "800x480-60"
     # D: 33.000 MHz, H: 31.280 kHz, V: 59.580 Hz
     geometry 800 480 800 960 32
     timings 30303 214 40 33 11 1 1
     rgba 8/16,8/8,8/0,8/24

Frame buffer device information:
     Name        :
     Address     : 0x5a001000
     Size        : 3072000
     Type        : PACKED PIXELS
     Visual      : TRUECOLOR
     XPanStep    : 1
     YPanStep    : 1
     YWrapStep   : 0
     LineLength  : 3200
     Accelerator : No

(setting the dimensions of the fb works too, it gets smaller for example 
if I set xres to 200)

Is there a simple app (preferably pre-compiled for arm debian or ubuntu) 
that uses the framebuffer? Or should I compile something, like links 
with fb support.
