No, most of basic X primitives aren't not really hw accelerated 
XAA is inadequate for recent graphic cards (status  
http://wiki.x.org/wiki/XorgPerformance). For example, for texturing
most of primitives are based on software algorithms (and Mesa do it faster).
With EXA it's better but it's not perfect yet (improving little by little)
