redhat 9.0 pb :insmod comedi

hi every body, I have a problem when I try to load the comedi module,
if some one can help me:

Using comedi.o
/usr/local/comedi-0.7.66/comedi/comedi.o: unresolved symbol remap_page_range

/usr/local/comedi-0.7.66/comedi/comedi.o: unresolved symbol init_mm

the /usr/local/comedi-0.7.66/comedi/comedi.o is just a link by tried without it first.
I tried with 7.67 but I have an error :remap_page_range!

thanks for your answer.
