I have used on a M2A-VM without problems the 2.6.27-rc6 from the
kernel.org, now I am using the 2.6.28-rc6 (well, almost without
problems, see http://bugzilla.kernel.org/show_bug.cgi?id=11599, and I
have yet another  USB-related problem with this mobo).

I'm on a different box now, I'll send you my .config tomorrow if you
still need it. But I always have all the modules I need built in the
kernel and module loading disabled, so I might not be affected by your
issue.

I've not seen yet the IOMMU message.

I did update the BIOS before installing Gentoo, there is one upgrade
specifically released to support Linux on the Asus support site.
