Firmware update to fix 3GB memory barrier

History

It appears that some iterations of this version supported only 3GB of RAM (mine), and some later ones supported 4GB. The very similar A1226 supported up to 6GB supposedly.

Is there an unpublished firmware update that will get me up to the 4GB usage at least? Would it be possible to apply a firmware for a very similar but later Mac to this one and have it work (I know this won't work for systems that are different)?

Thanks
