Can you please explain this a bit more in detail? I checked the source 
and README for CONFIG_PRAM and it seems to be reserving some space at 
the end of RAM. But I have only found reference to it in ppc and m68k code.

What would be the correct way to reserve some 2MB-4MB at the end of 
system RAM as a framebuffer for the integrated graphics device?

Thanks in advance

Matthias
