You are correct inthat I did not read the code. I guess I should have stated
my answer more clearly. However, I do know for a fact that modutils will _not_
load new style kernel modules. I found this out when I tried to upgrade to
2.5.75 without also upgrading to module-init-tools. I also know that the
differnces in the modules are more than cosmetic because my binary-only nforce2
network driver required a patch to be compiled against the newer kernels. Same
thing with the binary-only driver for the winmodem in my laptop.
I guess a better way for me to respond would have been that modutils is not
forward comaptible. Sorry for the mixup.
