  <H2><A NAME="9"></A>9. Driver Changes </H2>

<p>Changes since XFree86 3.3.2:
<ul>
<li>Fix transparent screen-to-screen copies on 546x.</li>
<li>The built-in screen saver now correctly blanks the screen
on 546x chips.</li>
<li>Driver prevents the use of the HW cursor on the 546x when
the screen height is greater than 1023 scanlines (fix to double
pointer problem).</li>
<li>CPU-to-screen BitBLT transfers disabled on the 5465.  This
fix should prevent 5465 AGP lockups.</li>
<li>Fixed mode display problem with 5480 at high resolutions.</li>
</ul>
</p>
<p>Changes since XFree86 3.2A:
<ul>
<li>A bug that caused a server crash with memory-mapped I/O operation
on some chips has been fixed.</li>
<li>Correct handling of dot clocks &gt; 85 MHz on the 5436 and 5446.</li>
<li>Preliminary support for the CL-GD7555 (no detection yet).</li>
<li>Support has been added for the CL-GD5480 and CL-GD5465.</li>
<li>32bpp mode has been fixed on some Alpine family chips.</li>
<li>Support for dot clocks up to 230 MHz has been added for Laguna
family chips.</li>
</ul>
</p>
<p>Changes since XFree86 3.2:
<ul>
<li>Enhanced acceleration using XAA on all chips with a BitBLT
engine.</li>
<li>Enhanced acceleration using XAA for the Laguna series (546x).</li>
<li>24bpp mode on 5430 is fixed.</li>
<li>Improved support for 754x, including support for LCD
stretching/centering.</li>
</ul>
