vm_map_insert fails, vm_map->max_offset==0?

Hi, is it possible to insert a new map entry to a process vm_map from a kernel module? I've tried to use vm_map_insert, vm_map_fixed, vm_map_findspace, but they all fail as the vm_map->max_offset is zero (0). I have looked at vm_mmap etc. but I don't get a clue what I'm doing wrong... BR, Teemu _
