hi,
I have a patch for unichrome(CX700, CX700M, CX700M2), which enable
hardware accelated StretchBlit (YUV->RGB).
NOTE:
1. this patch is against 1.0.1. for 1.1 and later, I think it should work.
since the unichrome driver have no change a long time.
2. this patch work well with VIA's viafb:
http://www.viaarena.com/Driver/linux-fbdev-kernel-src_2.6.00.03a.tgz
Thanks for your good work with DirectFB. :-)
