<li>Added returning correct information in GET_ACCELERANT_DEVICE_INFO (displayed in Haiku screenprefs panel);
<li>Fixed wrong PLL registerdefines for K8M800 and added seperate pixelPLL calculation routine: K8M800 now works correctly whereas previously you'd have a black screen (tested different resolutions, refreshrates and colordepths);
<li>Fixed blocking overlay hooks if current videomode is not supported (before overlay could kick in while it should not, resulting in bad video or desktop pictures);
<li>Fixed K8M800 video overlay: apparantly the engine was modified for this revision of the Unichrome video chipset: at least the 'V1' engine doesn't work here, while ' V3' does (using V3 now on K8M800).
