smdromod errors

I am trying to use the smdromod.o module
and it isn't working.

When I go to the console I see this:
----------------------------------------------
starting EMC MOTION PROGRAM -- smdromod.o ...
plat/rtlinux_3_0/lib/smdromod.o : unresolved
symbol get_pte_kernel_slow

unresolved symbol get_pte_slow
unresolved symbol __bad_pte
unresolved symbol __bad_pte_kernel
unresolved symbol __this_fixmap_does_not_exist

can't install it
----------------------------------------------

I have a BDI install on an AMD K6-2 550mhz

Is there a setting I need to set somewhere?
Is this a problem with the program code?

Any help will be greatly appreciated.

Thanks,
Allen F
