I haven't been in this situation, but one thing I know from the audio
groups is that if you share an interrupt with your audio and other
devices, or worse, between video card and other devices, you will have
problems. The number one thing I would check is that any devices your
presentation will depend upon should have their own irq. It is sometimes
possible to share irq without problem, but not sharing gives you a lot
more predictability. Also, turn off cron and anacron daemon during the
presentation. If you are in RH, you can go to /etc/rc.d/init.d/, and use
"./crond stop", or "./anacron stop" to disable them until the next
reboot (or till you give them argument start).
