I don't see how it matters whether the block diagram says the SDRAM
controller is 32- or 64- bit; as I said, I've tested the memory bandwidth
of the machine and it is exactly correct for a 32-bit, 33MHz bus, as I
said before.

No, I won't waste my time by doing that.  For one thing, it's a completely
crappy test of memory bandwidth; for another, as I *already said*, the
machine has the memory bandwidth you'd expect with a 32-bit, 33MHz pipe
between the CPU and memory controller, and, as I said, I know that because
I tested it (with a benchmark that doesn't suck, not the one you cut-and-
pasted from somewhere and are insisting that I run).

Why is it so important to you to waste so much of everyone else's time
trying to seem like you're knowledgeable?
