Do you mean the configuration like this?

option XIP_ROM_SIZE=65536
    option XIP_ROM_BASE=0xf0000

Actually, I've tried this at first, and it was not successful.
I guess it is because fixed MTRR overrides the variable MTRR
setting (so states intel manual).
Totally disabling fixed MTRR (do everything in variable MTRR)
looks cleaner solution, but wasteful.
