[iPAQ] Does ipaq support mmap?

Hi,
     I am trying to write a module, who uses a mmap mechanism. I try to run
it well on my pc(redhat9, with kernel 2.4.20-8), but when I try to
crosscompile it for my ipaq( with familiar installed, kernel
2.4.19-pxa1-rmk6-hh30.), the crosscompile is successful, but when I insmod
on ipaq. It reported error: insmod: unresolved symbol: discontig_node_data
     I checked the code of my module, the error caused by the line:
     mem_map_unreserve(virt_to_page(addr));
     when I take this line off, the module can be inserted. but I have to
use this line, can anyone why this error happened or give me some advice.
      Thank you very much! Hope the suggestion. Thank you.
