I am not sure when it stopped working.

I recommend the attached patch to kernel/params.c All the work was done 
to setup the file and maintain the file handles but the access functions 
were zeroed out due to the #ifdef.  Removing the #ifdef allows full 
access to all the parameters when CONFIG_MODULES=n.
