spidev module load problem

I can't load spidev module. Modprobe spidev doesn't return any error, but module is not loaded.
I'm using raspberry pi model B.

Did you uncomment
#device_tree_param=spi=on
in /boot/config.txt ?

Thank you. It's solved. I didn't know about it, because i followed guide on enabling spidev prepared for rapsbian. I didn't find anything for arch. Could you post link to some reliable resource i can use?

You followed an outdated guide since them a d us switched to fdt kernel. Google raspberrypi fdt kernel documentation.
