68HC11 with flash 2

I would like some advice on using Flash memory with the 68HC11. The 
objective is to store the code in Flash memory so that I could update new 
revs via serial download. A kernal would have to reside somewhere and I'm 
not sure if I can put in 6811 EPROM and then switch back and forth from 
internal to xternal mode or if I can keep it in the Flash, in a 
non-erasable block. Any real life experiences would be greatly appreciated.
