Default Bug#494144: Significant problem

severity 494144 serious
thanks

I think we have a very severe problem here that must be fixed before Lenny is
released. There may be a solution around that I don't know or see that lies
outside of the kernel and thus the bug should be reassigned, but still I think
this needs a fix before the release.

Now to my reasoning, :

Jordi already pointed out there was a change in kernel
behaviour with 2.6.26 in that the kernel default when not finding symbol
version information. Up to kernel 2.6.25 the kernel called itself tainted and
accepted the module. Since 2.6.26. the kernel throws an error. There is,
however, a way to insmod modules without version information, namely by using
"modprobe --force". But this is no longer possible because the kernel is
compiled without setting CONFIG_MODULE_FORCE_LOAD.

This has an effect for all out-of-tree modules, I stumbled upon it by looking
at virtualbox-ose-guest-modules. There simply appears to be no way at all to
include the vboxvfs module which depends on the vboxadd module.

I might be wrong and like to hear what I missed, but if I didn't miss anything
we are in must-fix situation.
