Many of them are tunable via /proc.

eg,

cat /proc/foo/bar

to read it, and

echo "baz" > /proc/foo/bar

to change it.  But there's no integrated tool to see and change everything
beyond that.  If you're bored, writing one would be a good way to gain Linux
fame ;-).

For example, shmmax can be tuned like this.  Look at /proc/sys/kernel/shmmax
(at least with 2.2).
