By default, 2.2 only sees 1GB RAM in a machine. Some of that is
reserved for kernel use, so you wind up with somewhere around 950MB of
actual available RAM maximum under the 2.2 kernel. You can recompile
the kernel to support up to 2GB of physical RAM.
The 2.4 series will recognize up to 4GB of physical RAM with the default
build, and can use special highmem access methods to see up to 64GB of
RAM if you rebuild the kernel with that option set.
Of course, these are both specific to 32-bit architectures like Intel.
Other platforms behave differently.
