Lilliput USB touch screen

I've successfully got the display on my Pi, so the next one will be for the Pogoplug. but I aim to get the touchscreen to work as well.
Display requires module fbcon, and xserver-xorg-video-displaylink (which has to be compiled)

Lots of hints are here

Two months and some progress.
And some stuck points too.

I sorted out the boot order problem which prevented my main install from booting, including copying files from a newer image but not the kernel, because I wanted my compiled kernel to run with the udlfb driver.

Then tried to install the xf86-video-displaylink driver. It won't compile on the armel platform, although it compiled for the armhf with the same xorg versions.

At this point I had the choice of a green screen or a login (slim) screen.
The system didn't respond to keyboard or mouse input.
After finding a compiled armel driver from ubuntu I installed that with dpkg. After that I only got the green screen and no login screen - even after I'd removed the package!

Next stage - autologin with slim.
I can operate the touch screen (with reversed axes).
I can't actually get a program from the twm menu to start.
I'm still lost about the failure of the mouse and keyboard towork - they certainly are found by lsusb.
