<li>Added 256Mb RAM detection;
<li>Improved startup code: this should (could) fix random trouble on some cards like for instance hardcursor trouble on especially laptops;
<li>Added dualhead support (use Mark Watson's 'G400 Dualhead Setup' from BeBits for now);
<li>Updated mode granularity and max virtual size checking/limiting to adhere to new CRTC setup for dualhead cards;
<li>Updated mode granularity and max virtual size checking/limiting;
<li>Added dualhead support for 8- and 15bit colordepths;
<li>Fixed move_display distortions in virtualscreens especially visible in 8-bit colordepth (for both heads);
<li>Added 'overlay follows head' for dualhead stretch and switch modes: if more than half the overlay output window is on a screen, that screen gets the overlay output;
