I can't do much more than share my experience but perhaps that will be enough. I am currently using a G550 with XFree86 v4.3.0. The hardware overlay works very well for me, i.e. I get 24 plane TrueColor visuals and an 8 plane PseudoColor visual. I have done 2 things beyond default config to make things work well:
1. Add this line to Device Section of XF86Config: Option "Overlay" "24,8"
2. Add -cc 4 to X command line at startup.
The first thing turns on the overlay support and the 2nd thing makes things work better but I'm not completely sure why - something to do with the default visual of the root window.
The only drawback (and this doesn't bother me at all) is that 3d stuff (DRI, GL?) doesn't seem to work with overlay turned on. I have tried various combinations of stuff and I can get the 3d stuff and overlay to work independently but not together.
Hope this helps.
