Hi guys (axel),

Hope this list still works (it's quiet here?)

Axel, if you need info about overlay, I think I might be of service.

For instance, the B_OVERLAY_COUNT hook _does_ serve a purpose, though 
its not used on R5/dano:
The driver is required to report the _number_ of overlay units the 
hardware has. If I have two, i'll report two. This means two apps can 
use overlay simultaneously, and two output windows using overlay will 
be created which are totally independant from each other.

BTW: please remember to ask for the hooks after every new mode set... 
(just like as it is with acceleration hooks)
