I don't think its the right solution. According to the Debian Policy
manual Provides: is meant to maintain the dependency graph when a newer
(and renamed) package provides the same support.

In this case, your powervr dkms package has a hard dependency on
linux-headers-omap4, and there is no other package that provides that

I think the real issue are the Recommends: in the dkms package itself.
Given that it is now being used with a variety of kernels, the
recommendations are kind of bogus. Adding a new linux-image* and
linux-headers* recommendation for every new flavour of kernel doesn't
really scale. If dkms dropped all of its recommendations then I don't
think you'd be having the issue where apt-get wants to install
superfluous packages.
