I am using debian unstable.  This works for me :

1) Preparing MOL using debian source-packages and the patch :
(removing all the debian mol* packages, we'll rebuild them)
----------------------------------------------------------------------------------------
$ apt-get source mol mol-drivers-macosx
$ wget http://dev.gentoo.org/~josejx/mol-0.9.70-nopriority.patch
$ cd mol-0.9.70
$ patch -p0 <../mol-0.9.70-nopriority.patch
$ dpkg-buildpackage -rfakeroot -uc -b
$ cd ../mol-drivers-macosx-0.9.70
$ dpkg-buildpackage -rfakeroot -uc -b
$ cd ..
$ su -c "dpkg -i mol-modules-source_0.9.70-20_powerpc.deb
mol_0.9.70-20_powerpc.deb mol-drivers-macosx_0.9.70-1_powerpc.deb"
---------------------------------------------------------------------------------------------

2) Building kernel and mol-module :
-------------------------------------------------------------------------------------------
# apt-get install linux-source-2.6.xx
# cd /usr/src
# tar jxvf linux-source-2.6.xx.tar.bz2
# tar zvxf mol-modules.tar.gz
# cd linux-source-2.6.xx
# cp /boot/config-2.6.* .config
# make oldconfig    or    # make menuconfig
# make-kpkg clean
# make-kpkg --append-to-version=-yyyymmdd --revision=2.6.xx-x
kernel_image modules_image
(2.6.xx-x is the debian version (see
/usr/src/kernel-source-2.6.xx/version.Debian))
# cd ..
# dpkg -i kernel-image-2.6.xx-yyyymmdd_2.6.xx-x_powerpc.deb
mol-modules-2.6.xx-yyyymmdd_*+2.6.xx-x_powerpc.deb
-------------------------------------------------------------------------------

Best regards,
Bin
