Using AMBER prmtop in cp2k for both FF parameters and connectivity

[Ilyas Khaliullin]

Seems like next doesn't work for me:

  &MM
    &FORCEFIELD
       PARMTYPE AMBER
       PARM_FILE_NAME ahx.prmtop
    &END FORCEFIELD
    &POISSON
      &EWALD
        EWALD_TYPE SPME
        GMAX 50 50 50
      &END EWALD
    &END POISSON
  &END MM
  &SUBSYS
    &CELL
      ABC 60.0 60.0 60.0
    &END CELL
    &TOPOLOGY
      CONN_FILE_FORMAT AMBER
      CONN_FILE_NAME ahx.prmtop
      COORD_FILE_FORMAT PDB
      COORD_FILE_NAME ahx.conv.pdb
    &END TOPOLOGY
  &END SUBSYS

CP2K hangs after printing some CELL related information.
I've uploaded my input, structure and prmtop files here as
http://groups.google.com/group/cp2k/web/AHX.tgz
Could anyone, please, look through them and give me some advices?
