The apm driver uses the XAA (XFree86 Acceleration Architecture) in the SVGA server. It has support for the following acceleration:

• Bitblts (rectangle copy operation)
• Lines (solid, single pixel)
• Filled rectangles
• CPU->Screen colour expansion (text accel). Not for 6422.
• Hardware cursor

All in 8, 16 and 32 bpp modes. No 24bpp mode is supported. Also VESA DPMS power save mode is fully supported with "standby", "suspend" and "off" modes (set with with the "xset dpms" command).
