If you're running a 64-bit kernel, you can't make vm86 calls. At the 
moment, vbetool requires that. I'm looking at porting it to use x86emu 
on non-x86 systems, but haven't been able to get it to work properly 
yet.

There's a video_post program that should also be mentioned in the docs. 
It uses x86emu, but I'm not convinced that it's entirely correct. 
Implementing the same functionality in vbetool shows different 
interrupts being called in lrmi mode and x86emu mode.
