Map the default 128MB of Z3 Fast on Kick 1.3

This assumes that the original Z3 Fast map line in the config has not been edited.
Z3 Fast is autoconfed before this on newer Kickstarts, so they're unaffected by this as the memory range will no longer sit around at $10000000.
1.3 PiSCSI autoboot still doesn't work.
