recent OpenArena/ iquake3 problems

[Jakub Lach]

Hello.

After recent (~16May) mesa/drm update OpenArena 
and ioquake3 are hanging when exiting/changing texture 
quality.

log:

Started tty console (use +set ttycon 0 to disable)
----- CL_Shutdown -----
RE_Shutdown( 1 )
Render thread terminating
Assertion failed: ((run->regs_mask[elm] & (1U << bit)) == 0), function

error: [drm:pid1071:gm45_get_vblank_counter] *ERROR* trying to get vblank

Dropping master

I'm using FreeBSD 8.0-CURRENT #0  r192601M amd64 
with ports up to date. (xf86-video-intel 2.7.1 @ X4500). 
I'm under impression that support for GM45 is official 
as of FreeBSD 7.2.

After update to xorg-server 1.6 OpenArena and ioquake3 
were missing some textures (OA and Quake III logo in menu 
respectively + models in player settings not showing up), 
but those problems were not major, as they were not
impairing ability to play those games :)

Now after recent updates those problems are not occuring 
anymore, but 

Assertion failed: ((run->regs_mask[elm] & (1U << bit)) == 0), function
arena_ru
_reg_dalloc, file /usr/src/lib/libc/stdlib/malloc.c, line 2543.

is more annoying.
