How did you disable it? The message "uma_memory_start=...." shouldn't
appear if CONFIG_GFXUMA == 0.

Help us understand what the desired behavior is. I'm looking at
dbm690t/mainboard.c wondering why uma_memory_size = 0x8000000; when
CONFIG_GFXUMA == 0. It doesn't make too much sense to hard code the address

HIGH TABLES just puts the ACPI tables in higher memory. It's not that bad,
but there are a few kinks to be worked out.
Something else I don't understand is why UMA allocation is saved until
enable. Shouldn't it be done with resource allocation? It doesn't make
sense to do it after the tables are written.
