hi!
I changed inelegantly the configure script to get a vm-display-fbdev and...
...came to understand, that there are more issues with Cog + fbdev 
(below is the make output).

Now I wanted to put it in a general question: are there efforts to 
maintain the vm-display-fbdev for CogVM? I guess there is little need 
for it in general, but in some cases it is nice to have (for building 
embedded or tiny systems the linux framebuffer is nice; sleak, confless).
Can anybody help me? Thanks.

Cheers!
