This is a case of a wiki page in need of an update because it only makes sense 
if you already know what it means ;-)

Note the first line on the page:
"NOTE: These only apply to Linux kernel 2.6.24, 2.6.28 has different paths 
(see below)"

The #Accelerometers link you were given points to the paths for 2.6.24 which 
have explanations, but aren't used by any current distro. Below that is a 
section that says what each path from 2.6.24 changed to in 2.6.28 and later, 
and are used by all current distros. Scroll to the very end of the page and 
you'll find the answer you were looking for.
