I would really like to see either that, or support for bochsbios again.
Hurd is not able to boot correctly without 32bit pcibios support, and I

Also 085debd93f52d36381ea13ef27e7f72e87fe62f5 could be interesting in a
new stable release, this fix comes from a problem detected on an image 
that was working with 0.11.x.
