That kernel has not been built with "High-memory" option(s) enabled.
Without special options turned on at compile-time, the Linux kernel (due
to various long-winded architectural details related to Intel processors
and legacy of those ancient 8088 days) can only see about 900MB of RAM
total.
Recompile the kernel with highmem enabled and you can use either up to
4GB of RAM or up to 64GB of RAM. Use the "4GB" option unless you
actually *have* over 4GB of RAM as there is a performance penalty using
the 64GB highmem option.
If you want to use a stock kernel, you'll have to find one with the
"highmem" option enabled. It might be called something like
"enterprise" kernel, depending on your distro.
