I think that will not fly with CONFIG_X86_PAE. In PAE mode the 3rd pmd (for the 0xc0000000 => 0xffffffff kernel address range) is shared, anything but 0xc000000 most likely needs some more hackery than just changing PAGE_OFFSET. As the whole point of this split patchery is to avoid highmem in the first place it maybe makes sense to have some "optimize for 1/2/4/more GB main memory" config option which in turn picks sane PAGE_OFFSET+HIGHMEM+PAE settings?
cheers,
Gerd
