"Modules Oops" workaround for 2.1.26

I disabled the CONFIG_MODVERSIONS ("set version information on all
modules") option in my kernel configuration and recompiled everything.
Since doing so, depmod, modprobe and insmod seem to work again without
segfaulting.

depmod -a was previously segfaulting in the same way that many other
people on this list have noted (dump attached).

I'm running 2.1.26, libc-5.4.17, binutils 2.7.0.9, ld.so-1.8.9

I hope that this will be helpful in debugging the problem.

Here the type of oops that 'depmod -a' previously was causing:
