When will that be available (V. 2.2 ?)? I hope it supports all VESA modes.
And double buffering functions for cards with enough memory e.g. 1 MB card 
in 800x600x256 or 640x480x256 mode. 512x512x256 color mode support would be 
nice for me too (with use of 1024x1024x256 image memory and 512x512
window). VESA support is really important, but in addition to that there
could be drivers for most common SuperVGAs which doesn't support VESA.

GNU C/C++ 386 compiler supports cards based on Tseng 3000 and 4000 chips.

It sounds too hard to start writing a driver if one wants to buy a compiler
to make graphics programs without any knowledge of the graphics hardware or
being novice in C/C++.

Only in U.S.A. :-( ?
