As far as I know, as Gentoo does, it does not handle it. I would suggest a way similar to the Intel way:
1) a package like microcode-ctl, let's say: amducode-ctl with a simple init script that manages to load the microcode module on boot (optionally keeping it after the microcode update). 2) a package like microcode-data, let's say: amducode-data that ships the latest AMD microcodes for AMD64 CPUs. If we want to provie less options, AMD microcode really is simpler to handle than the Intel ones, according to the AMD microcode tarball in their site, installing it is as easy as: # tar xf /path/to/amd-ucode-2011-01-11.tar # mkdir -p /lib/firmware/amd-ucode # mv amd-ucode-2011-01-11/microcode_amd.bin /lib/firmware/amd-ucode # modprobe -r microcode # modprobe microcode So it would be enough just a single amducode-data package and inserting microcode in the default modules. The Sabayon installer should choose the correct setup during installation. I am going to test this configuration, sooner or later on my AMD machine, unfortunately I will not be able to do this in less than a month. By the way, irqbalance not only provides a nice performance boost, but it is also powersave aware, balancing interrupts not to wake CPUs that have been turned off to save power, it is a very nice service to have into multicore system, in my opinion it is really not server-oriented.
