problem with loading kernel modules during booting in powerpc32

[Stas Timokhin]

         Hello !

  Some modules aren't loaded during boot via /boot/loader.conf (but some are
OK), but there are warning message for all of them:
>
loading required module 'kernel'
module 'kernel' exists but with wrong version
>

Here is my /boot/loader.conf:
ipfw_load="YES"
cuse_load="YES"
netgraph_load="YES"
ng_socket_load="YES"
ng_ether_load="YES"
ng_iface_load="YES"
ng_ipfw_load="YES"
ng_tag_load="YES"
ng_bpf_load="YES"


And kldstat afer booting:
Id Refs Address    Size     Name
 1   10 0x100000 fab7ac   kernel
 2    1 0x10ad000 17f98    cuse.ko
 3    1 0xd17ae000 44000    ipfw.ko
 4    1 0xd17f4000 15000    ng_socket.ko
 5    2 0xd1809000 20000    netgraph.ko
 6    1 0xd1855000 13000    ng_bpf.ko

So you can see that some modules are loading properly but some aren't.

Loading any module after booting via command kldstat are successful.
