<ul>
<li>Added full 2D acceleration for all remaining cards that did not have that yet with this driver (still largely untested);
<li>Fixed a long standing problem with MagicMedia (all NM2200 and later) cards with overlay: buffer width is programmed correctly now. Can't believe I didn't see that before!
<li>Updated NM2200 and later cards workspace virtualsize restrictions for accelerated modes: it turns out these cards engines have the same restrictions as most older ones, being 1600x1024 resolution;
<li>Updated overlay scaling restrictions: officially the cards support upto and including 8x upscaling.
</ul>
