Sorry this is a Linux kernel issue which is way beyond my limited 
knowledge.  Basically you will want to find the sources for the profil() 
function in the kernel and then examine them to see if you can change 
the sampling frequency.  You will then have to rebuild your kernel with 
this changed function in it before you can start generating profiles 
with greater frequency samples.
