Dependency error in virtualbox-ose

[Gary]

I attempted to install virtualbox-ose on a fresh Hardy install, and it tries to roll back to a previous kernel version even though an appropriate virtualbox-ose-modules package exists for my kernel. Telling it to install the correct virtualbox-ose-modules package with virtualbox-ose works around the issue, but it's still confusing.
