[coreboot] [patch] [v3] try to get new x86 real mode code working again

[Stefan Reinauer]

Since people start noticing that I broke v3...

The rewrite of the realmode vga init code broke v3... I tried to fix it
a while back, but I stopped when I got the attached patch.

The problem is there is not IDT yet in v3. Anyone willing to look into
adding that? If not we should split the util/x86emu directory again for
v2 and v3 and back out my rewrite in the v3 tree.
