follow-up: geode driver on GX2: no VGA signal (Lippert Literunner2 board)

Dear folks again,

Lippert support had been kind enough to reply fast (emails off list), 
here's the summary what they wrote:

a) support for the GX2 via geode driver with Xserver version1.7.7, as 
shipped with Debian 'squeeze', seems broken. No signal at VGA, no signal 
at LVDS (Lippert support cross-checked this)

b) it used to run with the 'nsc' driver, which will not be shipped with 
Debian 'squeeze' any more. According to the Xorg website, 'nsc' is 
deprecated and its features are / will-be taken over by 'geode' driver

Now, the LX is supposedly faster/nicer, but, IMHO, it would be sort of 
Good Thing to get the geode running on the GX2, whose support may 
otherwise be drifting away in newer Xserver releases. If someone feels 
it'll be worth filing a bug report, I'm more than happy to support that 
with testing, should someone closer to the GX/GX2/LX inner workings take 
the helm. Other folks with GX2 may be interested in this too - ?

any comments welcome
