Ah! I had thought that udev already had been installed by  
debootstrap... Sometimes things are much easier than one thinks :)

Sure. I think there is some activity on qi-hardware.com They use the  
same series of processors for the NanoNote and maybe we can copy some  
nice stuff...

Or look what the error means... Basically I am doing all this to learn  
Kernel hacking and debugging :)

I have not seen that yet - maybe it is a problem with the HSYNC timing  
not 100% in line with the LCD specs.

I have to add the above mentioned packages (plus some others) and then  
I can make the debian lenny rootfs available for easy download. Based  
on that, I hope there will be many differnt "Distributions" with a  
good selection of GUI and tools. E.g. upgrade to Ubuntu should become  
possible. Adding printer driver. Adding Browser, Mail, PIM etc. That  
is the good thing of a rock solid package base like Debian.

BR,
Nikolaus
