With this patch pygame will fail to import module "pygame.mouse".
However I have tried to cut off import pygame.mouse in
/usr/lib/python2.3/site-packages/pygame/__init__.py
to force not to load mouse module.
Also I cut off all pygame.mouse.* calls from freevo.
No luck. Mouse still lives and is locked in freevo window.
So the conclusion is that mouse is initialized even we don't init
python mouse module.
One more investigation - SDL_NOMOUSE environment variable is only used
in some SDL frame buffer drivers and have no effect to x11 or xv.
Looks like there is no way to disable mouse, not in pygame, and seems
to me, not in SDL. The only way to disable it is xorg.conf, but this
will disable mouse on all displays and is not a reasonable solution.
Alternative investigation direction is not disable mouse, but free from
window locking. I found some strange pygame method:

I have tried to call pygame.event.set_grab(0) somewhere after
pygame.mouse.set_visible(1) in osd.py. But still no luck.
Any other ideas?
