@hamsternz accidently put this message on the wrong thing, so here it is;

Here's the change H/W 8b/10b makes in resource usage.

Single channel 800x600 colourbars

           H/W   S/W
Registers  724   878
LUTS       882  1397
Occupied   295   552

Four channels 800x600 white

           H/W   S/W
Registers  820   975  -16%
LUTS       940  1473  -36%
Occupied   320   562  -43%

It is all checked in now, and It should be all good for you to pull it.
