+After kernel commit:

+http://git.yoctoproject.org/cgit/cgit.cgi/linux-yocto-3.0/commit/?h=meta&id=9728c1b6a724daefc413b44e10253cdbb5e06d08

+It appears that the emulated colours in qemu are incorrect and that 
+the red and blue channels are reversed. This patch reverses that logic
+so the colours are correctly displayed on the versatile platform which
+doesn't support the BGR bit.
