I have this problem occasionally on two of my three Zotac IONITX-C
frontends.  They are identically configured as dedicated netbooting
frontends with 2GB RAM, an IR receiver, and nothing else.  The lockup
during playback is as you describe, a short burst of audio rapidly
repeating and the system otherwise completely unresponsive.  More
often, this lockup occurs while editing a cutlist (where there is no
audio to repeat), and rarely it happens on a menu screen.  I don't
believe heat is an issue, but I haven't tried monitoring it.  I always
suspected it was an nvidia driver problem, but I guess that's unlikely
if it's happening with your ATI graphics.
