Ok, since you didn't specify any details of what you're trying to do exactly in your original post - I did some googling and assume you're trying to install http://oprofile.sourceforge.net
From your error message - it looks like you have some options in /etc/modprobe.conf that conflict with the version that you're trying to install.
The best advice I could give would be to update both and try again, as what you're doing should work.
Reading from: http://oprofile.sourceforge.net/doc/...arameters.html
It states that if it's built into the kernel you can specify it at boot time, so you could try a kernel rebuild also (maybe the long way around though.)
Hope this helps.
