Uryvek z helpu v menuconfig:

***
If you are compiling a kernel which will never run on a machine with more
than 960 megabytes of total physical RAM, answer "off" here (default choice
and suitable for most users). This will result in a "3GB/1GB" split: 3GB
are mapped so that each process sees a 3GB virtual memory space and the
remaining part of the 4GB virtual memory space is used by the kernel to
permanently map as much physical memory as possible.

Takze bych taky rekl ze to neni 800, ale onech 960.
