Oh, in that case you can use kbdcontrol to remap those keys.

kbdcontrol -d dumps the keys and you are looking for
  104   slock  saver  slock  saver  susp   nop    susp   nop     O
'susp' is the bit that does keyboard suspend just make them all nop. -l
file I think loads the file, but the man page has all the details.
