How do 4 x 1GB sticks run on AM2 boards?

I guess you already got the answers you sought, but better to much than too little, right?

In my experience, AM2 platforms work really great with four sticks. I only had to compromise a few MHz, and the extra interleave and capacity compensate for the insignificant frequency drop. I think the biggest drawback to using four sticks is that the tweaking takes more time.

My 4x1 GB Crucial PC5300 CL5 are stable @ DDR2-1188 @ 2.27 v, and DDR2-1152 @ 2.1 v.
