Try this:
Edit cfg-common.h and find the line with "brightness".
The fourth parameter should say CONF_RANGE.
Change this to CONF_RANGE|CONF_GLOBAL.
Repeat for any other option you'd like to remain unchanged between files.

I haven't tested this just now, but I seem to recall that this worked
for me once upon a time.
