From the project's ChangeLog 1.10 25 October 2004, Simon Trimmer <simon@urbanmyth.org> updated with new microcode from Intel applied patch from Tigran for x86_64 support and some cleanups What I assumed in bug 67786 seems to hold for the upgrade to 1.10 - the archive contains one and only one intel-ia32microcode-*.txt - bumped sys-apps/microcode-ctl-1.09 to sys-apps/microcode-ctl-1.10 on my local system and it emerges flawlessly ;)
added to cvs, thanks
