compositing detection for r300

Browse source 
I've had missing compositing since about a week on my ATI x1300.

After a bit of debugging with the help of fredrikh and mgraesslin, the version string reported seems to be the culprit. I've special-cased the different version string for the R300 driver and it works again now.

The strings my r300 reports are:

DRI R300 Project
Mesa DRI R300 (RV515 7149) 20090101 x86/MMX/SSE2 TCL
1.4 (1.5 Mesa 7.6)

reviewed by fredrikh

kwin people, please have another look, I don't want to break anybody else's setup...
