Okay, so assuming that I will never upgrade this particular machine past 4GB, and that I won't be migrating the memory when I buy a new machine, am I right in saying that the optimum configuration is:
I'm about to invest (what for me) is a lot of money. I just want you all to know that I appreciate all your advice. It's nice to know that you are getting the best value for your money when it comes to RAM!

Yes, your first example is going to be faster than your second example.
So I suggest the first example that you gave:
Upper riser
DIMM1:1GB, DIMM2:1GB, DIMM3:empty, DIMM4:empty
Lower riser
DIMM1:1GB, DIMM2:1GB, DIMM3:empty, DIMM4:empty
I will say that this is a better way for two reasons, because it does leave slots open in case you do need to upgrade again and you avoid the higher latency of the slots 3&4 on each riser. The costs don't seem to be that much different anyway. Heck, if you needed 8GB, the costs aren't enough of a savings to justify buying 8x 1GB chips vs. 4x 2GB chips, at least in my opinion.
I think Hiro's statement covers mis-matched sets of memory, where you have different sizes of memory on the upper and lower riser. If you have all matching memory I think it will be fine the way you suggested.

Upper riser
DIMM1:1GB, DIMM2:1GB, DIMM3:empty, DIMM4:empty
Lower riser
DIMM1:1GB, DIMM2:1GB, DIMM3:empty, DIMM4:empty
rather than
Upper riser
DIMM1:512MB, DIMM2:512MB, DIMM3:512MB, DIMM4:512MB
Lower riser
DIMM1:512MB, DIMM2:512MB, DIMM3:512MB, DIMM4:512MB
because only DIMMs 1 & 2 on each riser are capbable of 256bit?
So even if I put in eight matched DIMMs, only DIMMs 1 & 2 on each riser will work at 256bit and the others will work at 128bit?
Jeez, confusing, eh?

Thanks for all the replies, guys.
