Just to update. I ordered Saturday morning and received the stick on Monday. Great shipping. I currently have a Abit BX6r2 running 192MB, one 128MB and one 64MB generic stick. I decided to put the Crucial stick in DIMM 1 and keep the others in place. Works perfect. 448 MB of memory! It is subtle, but the computer is more responsive. Rampage shows 200 to 150MB free, instead of dwindling down to nothing with 192 MB. Below ar some stats from MBM 5.
