Yes but load average?  CPU wait percentage? Are there processes in the
uninterruptible sleep state?

Is there any difference in the machine's behavior when you run the build
form a text-mode virtual console?  Maybe X11 is messing things up.
Sometimes even text scrolling across an xterm can bring X11 to its knees
and every process will then hang that's trying to communicate with X11.
 Maybe uninstalling the ATI drives will fix things like you say.
