memory model

what about simply:

* kernel is overlayed with RAM + EEPROM
* all the rest is flash

note that only the first 32kb can contain VM code, due to VM using 2
bits. the other 32kb is addressable, but only usable for tables etc..
not important now for PICs i use.

so ram max address space is max #x1000, data eeprom i'm not sure there
is a limit. but we have only #x100 and it's not used. what about we
map the flash to the upper 32 kb, and ram from the start? then eeprom
could be added later.
