you would need to compile a kernel with PAE enabled. Not really that
PAE = "Physical Address Extension"
/me flashes back to the 80's. Late night brainstorming meetings, generally
accompanied by ethanol. "I know, we'll add this extra bit so we can go
above 1 megabyte!" Then, the inevitable one-upmanship: "Hey, we can store
that bit in the keyboard controller!"
Coming in 2011: Segment registers!

[1] Being Engineers, it may be that it wasn't late at night. Maybe it was
an 8AM meeting.
[2] 1 MB is roughly equivalent to "640K", if that helps you recognize it.
[3] Maybe none of this matters anymore, now that memory management is
virtualized
[4] Who thought up this lousy 64-bit limitation, anyway? :)
