64 bit kernel in 32 bit system

[Bill Davidsen <davidsen tmr com>]

I have read that there will be a feature to run a 64 bit kernel in a 32 bit 
install of FC11. I'm curious about the number of things it would take to build 
such a kernel for FC10 (other than building the kernel, obviously).

Any input from whoever is does that part for fc11?
