The 4G of kernel address space are useful from 1Gb of ram

then the 1Gb of lowmem in the non-4g/4g kernel really starts hurting the
vm algorithms).
Any guidelines on when to choose the hugemem kernel on systems with 1GB
- 12GB of RAM (which is probably a large share if not the majority at
this point)?
