It is a limitation of the 32 bit architecture. If you want to use more memory, and you have a 64 bit chip, you can install a 64 bit distro. Some distro's like SuSE are biarch, and allow you to install 32 bit programs. SuSE will install the 32 bit version of Firefox for example, so that it is easier to find plugins.
You will also want to read the docs for the motherboard to see if there are any other ram limits imposed.
My new M/B (ASUS P5B WiFi Deluxe) supports 4 GB on board (4 slots), but I read in the book that win 2000 and XP can't see more that 3 GB. To use all 4 GB we must use the 64-bit versions of those systems, like server editions etc. Of course, there is nothing else than m$ for them. The world's limits are the m$ doors.
I wonder what a Linux system would detect with 4GB. My system is intel E6600, so I couldn't use the -64 versions made for AMD 64 architecture. Anyway, I have just 2GB on board.
