Could you please post your ps -Al, /proc/meminfo, and lspci output? I
know Red Hat has a lot of standard daemons (PCMCIA, ISDN, etc) that are
started by default - have you used chkconfig or redhat-config-services
to shut off unneded services?

The kernel also uses a lot of free memory for I/O caching - even my P4
w/ 1GB RAMBUS shows 90% memory consumption in /proc/meminfo. Caching is
a low-priority memory allocation - when the system needs memory for
active processes, it should give the memory to the process.

BTW, unless you are using a framebuffer kernel-level driver, X is
handled almost exclusively in userland. On SPARC32 (for example)
framebuffers are pretty much the only way to get X working, but mostly,
XFree86 and the X.org server that comes with FC2 use mostly user-space
drivers.
