When a memory module Is larger the nb supports it can be run are the max supported size.
The nb you have supports 512 MB per side, the 1 gb you have has 1 side with 1gb so you nb can't handle the full size, the 2 gb has 2 sides With 1gb, so the nb can use a total of 1 gb.
I committed a patch to handle this type of stuff for 440bx.
All you have to do is force the sides to the max supported, if any thing larger is detected.

Well, in the worst-case scenario, as a test, you can modify the
raminit and just force it to use only 512M. Just as a test. I do this
sometimes when I have ram issues.
