I have pulled the bigphysarea patch (as posted by Nick Martin for
kernel 2.6.9) towards the kernels 2.6.10 and 2.6.11.
Maybe there is somebody out there who can use it.
(it only suits the i386 kernel, I have not done this job for other platforms.)
First the 2.6.10 version is listed below, after this the 2.6.11 version
Have fun with it!

That should be: mem_resource.start = virt_to_phys(bigphysarea);
Otherwise you could get a collision?
