Could someone tell us why making the VDI would be such a performance gain ?

The TRAP API (like any other TOS system call) is very inefficient, and 
the VDI/AES is probably the worst. A new API, directly from the user 
programs to the VDI implementation would be far better, there is no doubt.

But why the VDI would have to be a kernel module ? Most of its work is 
to draw in the video memory, there is no need to switch to supervisor 
mode and play with the hardware or kernel internals to do that...
