Unable to modify /proc files in ubuntu?

I've got some instructions to modify one of the files under the proc tree. 

   echo 1 > /proc/sys/vm/legacy_va_layout

How is this possible under Ubuntu? I've tries a few styles of sudo command, but
nothing will work. Under debian I would have just done this as root. What is the
ubuntu way?
