I installed Red Hat 7.0 out of the box and my machine only recognized a
little less than 900 megs, I tried mem=2048M in lilo.conf, I also tried
adding it to the lilo prompt, and neither worked for me. I'm using a Compaq
Proliant 4-way SMP with 2 Gigs of RAM. I upgraded the kernel to
2.4.0-test8(I needed this for ATM reasons not memory) and recompiled with
BIGMEM support and then everything worked fine.
I am still pretty new to linux, so maybe I missed some config option.

You should not have to recompile the kernel in 7.0 for it to recognize the
4G of memory, unless there is something wrong with the kernel that ships.
6.2 will recognize 4G of memory out of the box with no recompile (been
there done that). The 6.2 kernel and I assume 7.0 kernel (I have not
tried 7 on a 4G machine) has the bigmem patch. If the kernel doesn't
recognize the memory add mem=4096M to /etc/lilo.conf.
