Well, from what I can tell, I haven't seen the above warning since, but 
it was neither easily reproducable. "Working reliable" is probably a bit 
too much. (-; No, the vertical position of the boot console is off, 
panning flickers, and the two-monitor case is close to non-working. But 
other than that, it works now regardless of whether the bios is set to 
internal or shared monitors.

So I would guess it works as good as it currently can. (-:

The harddisk of the R31 (the other laptop with the same dreadful 
chipset) died today, so I fished a "new old one" from our pile of junk, 
and re-installed Linux. It currently compiles the latest git, so please 
have some patience with a 1.2Ghz Celeron. Will be ready tomorrow, 
hopefully with more results for the "anti-flicker" patch.

Anyhow. This patch is currently *only* tested for the linear framebuffer 
alignment, and most certainly not "right". I believe its some sort of 
memory alignment issue, and I need to dig a bit deeper what exactly 
happens there.
