Update of /cvsroot/mplayer/main/drivers/radeon
In directory mplayer:/var/tmp.root/cvs-serv30203/main/drivers/radeon

Modified Files:
	Makefile radeon.h 
Added Files:
	radeon_vid.c radeon_vid.h 
Log Message:
radeon_vid: it's in first pre-alpha stage
Note: it's not public release and not test version.
It's simplest commit of unfinished and not working stuff
in hope to attract other developer to this driver.

(What is good: this driver is removable from driver list
and doesn't cause segfault !!!)
