Unless reading video memory has gotten substantially faster (i.e. the
same speed as main memory) I don't think vesa suffices for ANY use.
The way the X server is written, almost all common operations require
reading back from video memory if implemented in software. This could
be avoided by changing the implementation to do everything on a
mirrored buffer in main memory and only copy the final version to
video memory, but as far as I know that was never done.
If I'm wrong and video memory access issues have changed all this much
in the past 4 or 5 years, please ignore this message...

It's intended to work, but I don't know whether it does yet.
