Well, 0.9.70 is quite old. There have been some changes in the kernel
between version 2.6.11 and 2.6.12 that affect MOL. Maybe this is your
problem. See this message for a patch:
http://lists.maconlinux.org/pipermail/mol-general/2005-September/003855.html

I'd also suggest to use a newer MOL tarball that contains many recent
patches http://dev.gentoo.org/~josejx/mol-0.9.71_pre4.tar.bz2 Currently,
we don't have a recent 'official' version.
