Maybe I'm missing something. You select GFXUMA but nothing seems to depend on it?
is there something else out there that uses this variable?

Ah, hmm, I will have to look closer...... I just realized the add_northbridge_resources is not working eithor....
No one ACK this yet.

This is kind of a pre CAR patch to properly allocate "shared" graphics memory area.
CONFIG_GFXUMA is used in src/cpu/x86/mtrr/mtrr.c which is called by the cpu.
Attached is a revised patch which works well.
