Agreed. Given how much more common 1GB hardware configurations are compared to 768MB configuration, we could however think about adding a VMSPLIT_3G_OPT option that x86 has (also VMSPLIT_2_75G on ARCH_TILE), to allow using the entire 1GB of lowmem without going all the way to VMSPLIT_2G. That option would also let us use the entire 768MB on the machines that Yongtaek Lee is interested in.
