Hello,
I am getting this message when running a patched kernel:
BUG: unable to handle kernel NULL pointer dereference at (null)
Is there some kernel configuration item which enables getting
, instead "(null)", the proper value (I assume it should be a method name)
Regards,
Kevin

That is just what you get when the kernel dereferences NULL, isn't it?
(If the kernel dereferences, say, something halfway some struct, you'll
see a hex address instead of "(null)".) Assuming x86, see:
arch/x86/mm/fault.c:show_fault_oops() and lib/vsprintf.c:pointer().

Doesn't your BUG also print a backtrace that points at a (possible)
culprit?
