Or you emulate thier functionality.. but perhaps thats what you are 
saying.  Thats what X does.  LinuxBIOS has pulled the x86emu out into a 
standalone userspace app that we use to try and get video cards up 
across a serial console.  Currently that app is 400k (dynamic linked)

The plan though is to include that emulation ability into LinuxBIOS and 
400k is way to large.  The authors feel though that it can be done.  I 
think the core pieces aren't really that big.

It dosen't seem to work with my ATI bios though which is why I was 
interested in another implementation.  Word is that the current 
LinuxBIOS implementation has issues with int10 replacement and then 
calling back into itself.
