A second of google led me here:

I think you find the answer to your problem develops from here:
http://bugs.gentoo.org/show_bug.cgi?id=280282
And can be found here: http://bugs.gentoo.org/show_bug.cgi?id=286042

[..]
if you have 2.6.31 and want to use kvm-88-r1, kvm-kmod-88-r1 is not
required and you can use the in kernel modules.

if they release kvm-devel-89 for example, it may have newer kvm-kmod code than
what is bundled in the kernel.
