For anyone developing with KOL, Dmitry K did a - as yet unofficial - 64 bit Windows version that is sufficiently stable to be considered to be added to the official can obtain it here: http://yadi.sk/d/Z0uMP31_67nJY

If you are interested and know something about how to use KOL/MCK, plz test and let me know.

Remember to compile with at least -Mdelphi -Rintel -dPUREPASCAL Unicode version doesn't require -Mdelphiunicode but rather: -dUNICODE_CTRLS This is because KOL already had unicode before FPC.

p.s.:
ppcrossx64 outperforms dcc64 in size and speed, at least with KOL.
