You should make it real chipram, because ACA500 puts 1MByte of fastmem into the $c0.0000 area. The other 1MByte fastmem is reserved for Maprom'd Kickstart. If the trapdoor expansion is "fake-fast", then it will be disabled by the fastmem-overlay. Only the RTC of the trapdoor expansion would be usable, and you probably don't want that.
