Does that motherboard have IPMI support?
Could it be that some kind of SOL console or similar is enabled, and that simply tries to force the box to not leave text mode?

I would agree with you except that the undionly.kpxe I built more than a year ago based on commit fd6d1 does work perfectly, background image and all. Switching between video resolutions also works fine.
I built the same binary again today with the same commit and it has the bug.
I think it has something to do with my build environment and I am going to rebuild it today and see what happens.
