 It reads register 4e. Are you sure its not just the enable_flash_ich_4e()
 function that most other chipsets are using?

 Please remember: when testing this you need to test from cold start
 because flashrom does not reset the registers to their original state.

 Also, FFF80000-FFFDFFFF is not enough. You need to enable the range from
 FFFE0000-FFFFFFFF as well.

 Ignore the "Lower BIOS Enable" stuff. This is only required for 16bit
 operating systems and a really ugly mess.
