Maybe not entirely accurate to the original question, but....
I had a couple of 16 & 32mb simms laying around doing nothing, and i placed them in the 4000 which was equipped with 8 mb of 4x2mb simms....
The 4000's sees every simm as 4 mb, thus giving a 16mb of ram.
I think the Blizzard board will detect it like 128mb, if that's the maximum per slot. If not, maybe it sees it as true 256 mb.
It won;t blow if it doesn't work is my experience with hardware.
