Demos included in LibGGI and applications which I maintain (XGGI, 
Frodo, ggisyna and LinuxDoom/Heretic) are fine.

Functions in the generic-linear-* libs call the macro PREPARE_FB(vis);
before actually accessing the DirectBuffer, so we should only need to
change that macro if we wantto use the linear libs together with
accelerated functions on broken hardware.

Other than that I don't think any current code will be affected.
