It seems that sys-firmware/seabios has not been updated since release 1.8.2. The package upstream is currently at version 1.10.0 and the releases contain vital fixes required for proper operation of new versions of QEMU and KVM in BIOS mode. Probably Xen as well if system-seabios USE flag is enabled. The current version in portage (and on mirrors) is more than a year old and behind 2 major releases. Please update the requisite tarballs and ebuilds.

Fedora hasn't updated to 1.10.0 yet and we've been getting the precompiled seavgabios blobs from them. i'm not aware of any other location short of building our own which i'd rather not (to try to increase cross-distro compat).
upstream has released 1.10.1, and Fedora has done builds, so i've added those now https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e747c2787e38a9257e7444025bfccbd35231de71
