OK that is solved :)

That does not change things here... no OSD yet.
But i discovered a strange thing:
both with original patch04 and with the above modifications i _normally_
do not see OSD, but if i move the window or if the system is under heavy
load i am able to see the osd for _half a  second_ or so, it seemed to
me as a "z-order overlay problem": like if video was *above* OSD and the
latter is visible only when the window is redrawn.
Does this depend by my videocard drivers (even if OSD worked
with patch02) ? I tried with 24bpp and 16bpp with same results.
I paste here xvinfo for more details (XFree86 Version 4.2.1.1):
