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.

Cheers
