You might be able to *build* crash.o with "make modules", but if you try to install it, it's going to fail due because it won't be able to resolve the "page_is_ram" reference. There may be some other way to export a symbol from the base kernel without rebuilding the kernel. I have seen some 3rd-party modules (i.e., non-Red Hat) that load a "rogue" module that tinkers with its own internal exported symbol list after it is installed by overwriting its own exported symbols with the symbol name and address of un-exported base kernel symbols. Then, after the rogue module gets installed (and overwrites its own list of exported symbols), a second "real" module gets installed -- and the real module uses the illegally-exported (?) kernel symbols from the first rogue module. Seems like a violation of the GPL, but anyway, I don't have any examples of how they do it.
