[ydl-gen] YDL on PB17

[Norberto Quintanar]

>From <http://www.xfree86.org/4.6.0/ati3.html#3> "For all but Mach64
adapters, this driver still does not provide support for accelerated
drawing to the screen. This means that all drawing is done by the
CPU, rather than by any accelerator present in the system and this
can make opaque moves, for example, quite ``jerky''."
