You can still use vesafb with the generic software renderer, but you
will lack most hardware optimizations, specialy pixel format conversions.

There is an ATI driver since this time, I think. And DirectFB improves

DFB must be way lighter than X. In my case, it is nearly 80MB RAM less
(counting X + Xine - softdevice). CPU utilization depends on hardware
acceleration, WTR MPEG2. Nothing should impact CPU in DFB per se.
