That would be me. And indeed, the change in section is going to be a
problem, since on x86 the scanner will expect the sys_call_table to be in
the same section as init_mm, which will no longer be the case. What we
need to do is find some exported symbol in the same section, preferably
near the beginning.
Given a new symbol, there are a couple of approaches we can take to
determine when to use it. One is to simply always use the new symbol on
kernels 2.6.14 and newer. The other is to extend the control structure so
we can give the probe code more than one section to look at.

Well, does 2.6.14 have the exported symbols we're waiting for in the
