Take a look at Alessandro Rubini's allocator module. It's referenced in his Linux Device Drivers book (available online somewhere). Using this module in conjunction with the "mem" kernel parameter you can allocate as much physically contiguous, non-paged RAM as you want without modifying the kernel. The only caveats are that the module does not play well with big-mem kernels (> ~900MB RAM) and I haven't ported/tried it on a 2.6 kernel yet.
