Is there any benefit/point to enabling HIGHMEM when using this patch, assuming that physical memory is smaller than the address space? For example, when using VMSPLIT_3G_OPT on a box with 1G of memory.
No. In fact, there should be a (very) tiny performance gain by NOT enabling HIGHMEM -- things like kmap() should get simpler.
Actually, IIRC if you have an x86 CPU (or x86-64 running a 32-bit kernel) which has a no-execute bit, to support that (i.e. to have a more secure system) you need to use HIGHMEM64G, no matter how much or how little RAM you have.
