I find it interesting that I get a different node count than you.  I'm running
Rybka 32bit on my AMD64x2/3800+ with 128M hash.  I tried 3 different GUIs with 2
differnt starting buttons (Infinite analysis & go/computer with 40/1hr).  Fritz
and Shredder 9 UCI both give slightly different node counts when using Infinite
vs go/compute buttons.  Arena gave the same reading both times but they vary
from what Fritz/Shredder GUIs give for node counts.  I also note that I have set
the UCI hash setting for 128M hash in Arena but it shows 158Mb on the screen.
Here are my readings:
