Correct me if i'm wrong but Geode GX2/LX doesn't have MTRRs.
Cache is setup via MSR registers.
So all that MTRR stuf in tiny bootblok/coreboot is useless to Geode.
Which regions are used for tiny bootblock that need caching?
If no one beets me i will investigate this further after SeaBIOS Geode
VGA is ready.

Those i8042 warning at the beginning before warm reset comes from
There is a SeaBIOS kconfig option to turn off the ps2 controller.
