does anybody use Xen's ucode=-1 option successfully?
I'm trying to update the microcode before dom0 starts, since my dom0
doesn't have the xen microcode driver. I'm using a vanilla 3.12.x kernel
from kernel.org and to the best of my knowledge, the xen microcode
kernel driver didn't make it upstream yet.
It took me quiet some time as well to figure out how to get it to work,
but I finally sorted it out some time ago.

Could I by any chance prevail on you to write a patch to the
documentation or create a wiki page perhaps?
Ian, if you might lend me a helping hand to get things started, I am happy to write something up.

In terms of documentation - are you thinking about a specific man page and if so, what would I need to get that started? Or would it be a simple text file for /usr/share/doc? In any case, I'd actually prefer those options over a wiki as either of the former would automatically be delivered with every xen installation and therefore readily available to the user-base. Furthermore I have never myself created any webpages so far ... (I know, shame on me ...)

There is one caveat though: I currently only use XEN 4.3 which does not support the prepended file to the initramfs yet. Therefore it might make sense to postpone this until XEN 4.4 is considered stable by Gentoo and I am up and running with this version. What are your thoughts on this?
