[coreboot] [PATCH] improve realmode api

[Nils]

I brought back the GX2 code in to the code at:
svn://coreboot.org/vsa/trunk/gplvsa2
The biggest chunk of code doesn`t affect the LX code.
The resulting LX image is binary compatible with the old one.
But a few lines have to be selected for GX2 only.
I wanted to invetigate how to do that and send a patch,
but i haven`t had time.
I am focusing on the board till now.

Thanks,Nils.
