/usr/linux is a symlink to the Linux source tree that should be used for any
kernel specific stuff when building a program, driver/server or module. The
problem is that this link isn't automatically updated when you manually
install a Linux kernel, so you have to do it yourself.
Just point it to your 2.2.18-rtl tree, rebuild your module, and provided
you're not doing anything that's not compatible with the 2.2.x kernel API, it
should work. (Well, *unless* some makefile involved is using the physical
path to the 2.4.0 kernel, of course.)
