Mm, you *could* do that by doing a "manual" update of erasing the specific older version of the package and installing the new, instead of using rpm's normal update procedure. Actually this has been brought up before on the subject of kernel-module packages, on freshrpms-list IIRC. I wasn't excited about doing such a "manual" update from apt for this special case then and I'm not now either :)
<sigh> God this is going to be ugly.
Like really, really, really ugly.
