Problem with Poulsbo driver on 10.04

[Marcin Rosner]

Hello,

I have an Axiomtek PICO821 motherboard with Poulsbo chipset and Atom  
Z530 and Ubuntu 10.04 and .21 kernel.
I installed the poulsbo driver as it is written on  
https://wiki.ubuntu.com/HardwareSupportComponentsVideoCardsPoulsbo/  
but after that I can't start X anymore. After reboot Ubuntu comes into  
the splash screen with "progress
bar" under the Ubuntu, the splash screen is on for a fraction of a  
second, starts to blink splash->command line->splash and so on for a  
second, then I get a black screen and I can't do anything except of  
hard reset. recovery mode/failsaveX doesn't work anymore (I get the  
black screen at once).
I've tried to remove those drivers from recovery mode/netroot, but  
that doesn't change anything.
I have a newer kernel .23 that doesn't work neither after the driver  
installation.
I've installed the poulsbo driver on 9.04 and 9.10 without any problems.

I searched on the web, but it seems no one has such a problem.

How can I solve the problem?

Greetings,
Marcin
