Sorry.  (In 2.6.25, init_mm is marked as an unused symbol, and so whether 
it is exported depends on whether CONFIG_UNUSED_SYMBOLS is enabled).

I've committed a change which should fix this problem.  You can get get 
the new version (0.8.1) from http://web.mit.edu/ksplice/dist/ or from Git. 
(I haven't yet made the new version the default, so you won't receive it 
from the main Ksplice page).
