The way I understand it, 32 bit kernels have 4 GB of addressable memory, but they need to set aside some of that to be able to use things like PCI slots and such, so you're not actually going to HAVE 4 Gigs of RAM available.
If you want to use your full 8 Gigs, you'll need to use the 64-bit kernel. On the server, you're not likely to see any of the downsides of using 64-bit (like getting Flash and media codecs and such to work). OTOH if you already knew that and DID use the 64-bit kernel, I'm flat out of ideas.
