Changes since XFree86 3.3.2:

• Fix transparent screen-to-screen copies on 546x.
• The built-in screen saver now correctly blanks the screen on 546x chips.
• 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).

• Support has been added for the CL-GD5480 and CL-GD5465.
• 32bpp mode has been fixed on some Alpine family chips.
• Support for dot clocks up to 230 MHz has been added for Laguna family chips.

Changes since XFree86 3.2:

• Enhanced acceleration using XAA on all chips with a BitBLT engine.
• Enhanced acceleration using XAA for the Laguna series (546x).
• 24bpp mode on 5430 is fixed.
