It appears that the larger part of our user base is running a 2.4 series kernel,
and will be for quite some time. Considering this, and our position that
testing kernels are not offically supported, I think we should give priority to
fixing bugs that affect the most users.

I find this acceptable under the condition that it is properly documented in
both postinst and ChangeLog.

The one caveat I can think of is GRP. Will we distribute a package for both
kernels? How does portage choose the right one?
