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.
