if you guys dislike /sys/module/kernel/* for core stuff, then you  
should do the change as soon as possible since userspace relies on it  
for a lot of tasks. Even I started using it. However I only want one  
general place for kernel/module parameters. A symlink might help us in  
the meantime to get the transition done smoothly.
