    non-off-screen bitmaps? that means... on screen, and that under no
circumstance I agree. Maybe you wanted to say: drawing into off-screen
bitmaps application side ?
    And... to reformulate my earlier question: Is it equal good to have
context switching at server side or at driver side? Isn't the one at driver
side more costly?

    I want VESA mode to be the only fallback solution. The drivers should
all have 3D HW acceleration.
