We may have discussed this before, but I think this is the model
that you can upgrade to the 2010 firmware and significantly
increase the bus if you get faster RAM? I think this would be
worthwhile, the faster RAM is probably cheaper than what you're
using now, and you'd be ready for a CPU upgrade if you ever felt it
was necessary. See this:

This looks like a very interesting project and after reading the
piece I'm trying to find the download for this modification but I'm
not having any luck?
It's probably here, you'll need to register to see the download link:

Also is the RAM speed issue of concern to me?
Probably not.
1066 to 1333 is a greater than 30% speed bump, BUT, it requires the
CPU upgrade in order to get this RAM speed bump. The CPU communicates
with the RAM directly, and the speed is set by the CPU, so there's no
need to get faster RAM until you get faster Windmere CPUs. For that
matter, it's probably not worth doing this firmware update unless
you're going to replace both the RAM & CPUs because otherwise the
advantage would be very minimal (audio out fix perhaps?) and the
drawbacks large (your install DVDs don't work any longer).
