I'm mostly using vsmsetup.c That 0x18 should be 0x10 I think.

I think the gdt in vm86.c needs to be made identical to the one in stage0.S.

Not sure yet. But there is a problem here.

yes, we can do this, just go ahead and make a cosmetic patch.

Why is the data segment for the VSA in 16-bit mode set to x40?

The vsmsetup.c in geode is mostly vsmsetup.c from v2. The only bits
from vm86.c that are used are code that was basically identical.

I'm still puzzled.
