The 32-bit generic .i686 kernel sees what the BIOS tells it is 
available.  If you google it, you'll find a couple of good explanations 
as to why 32-bit generic .i686 kernels don't see (or can't use) all 4GB, 
it is usually something less (like 3.5 or 3.75 GB, depends on the 
motherboard).  In order to use *all* 4GB of RAM (or more), you need to 
use a PAE enabled kernel instead of the generic .i686 kernel.

.x86_64 fedora kernels do not usually have this restriction and can use 
all installed ram.  If your CPU is 64-bit capable, that's a good reason 
to run it in 64-bit mode.
