Same here, with SLES9 and kernel 2.6.5-7.145-pseries64

And on RHEL3 (2.4.21-27.0.2.EL) I get lots of warings/errors in the style of:
/lib/modules/2.4.21-27.0.2.EL/build/include/linux/byteorder/swab.h:206: 
warning: left shift count >= width of type

I added -m64 to the compiler commandline and got a module which does not 
want to load:
[root@rhel3 osi_probe]# make check
/sbin/insmod ./osi_probe.o probe_debug_tag=6824 sys_call_table_addr=0xc0000000003b6f70
Warning: loading ./osi_probe.o will taint the kernel: no license
  See http://www.tux.org/lkml/#export-tainted for information about tainted modules
