You're using the 32-bit version, right? The design of x86 architecture
(i.e. it's not FreeBSD's problem) is such that a part of memory
addresses needs to be set aside for hardware uses, such as the PCI bus,
AGP memory & others. This manifests as "holes" in memory that are not
accessible to OS.

There are two possible solutions: you may try compiling a 32-bit kernel
with PAE (but not all drivers support PAE), or install the 64-bit
version of FreeBSD.

Well I hate when people say this, but I'm going to say it.. :)

When I did a default install of ubuntu, it saw all 4 gigs without a
hitch. So does that mean it already includes PAE, or something else ?

Aside, I will read up on PAE.  I'll read up about 64 bit as well, I've
been hesitant to make the jump only cause any word of mouth i've heard
said  that it's not ready for production. Maybe that's off base, it's
only what "i've heard"

Thanks !
