Aye, squeeka, a two hour render time is bliss! My most complex scene, this stupid hunting cabin by a pond, takes that long to PLOP render! One day I'll finish it, but might I suggest perhaps taking a nap while rendering? (I know, I know, plenty of time for sleep when we're dead, but it's just an idea!) Also, I'm sure you know this but in case you didn't, if you have multiple instances of Bryce open, it will slow down ALL of the renders. Of course, you can set priorities with XP, but believe it or not the processor can only handle so much. And a 1.3GHz machine is plenty fast for Bryce...
