[ut2004] still no love with ut2004 amd64

[Dean Hamstead]

hmm could now be an openal setting

having turned off sound completely in the ut config file
ut seems to work first time i start it up. (alas if i
exit and run it again is segfaults or the kernel page
faults)

turn openal on and the system reboots

at first it thought it was becuase i tried
turning 'renderaccell' 'true' on in the
device section of xorg.conf. but when i turned
sound back on same system crashes. turn sound off
works, on crashes. turn renderaccell back off again
ut works. (as i said, on the first execution)

so i gather something is up with openal or
openal talking to alsa.

but why its crashing after the first execution is
and interesting problem also.
