Unfortunately, that's not an option.  We need to be able to reserve/allocate
pages in a driver's init_module() function, and I don't mean drivers that are
compiled with the kernel.  We need to be able to ship a stand-alone driver that
can work with pretty much any Linux distro of a particular version (e.g. we can
say that only 2.4.14 and above is supported). 

For the time being, we can work with a patch to the kernel, but that patch be
relatively generic, and it must support our dynamically loadable driver.
