When building the VirtualBox modules using linux-source-3.7 from Debian
Experimental, the build will fail without IOMMU support being configured-in:

----------------
An interesting aspect of this is that the VirtualBox modules build just fine
against upstream Linux 3.5.7 /without/ IOMMU being configured-in, but does
fail for upstream Linux 3.6 and 3.7.
As all of the hardware I own does *not* support IOMMU, having to configure it
in to be able to compile the VirtualBox modules is counterintuitive and thus
seems like it's a bug, so I'm writing this mainly to let other users know
about the problem. I'm not sure what severity this should have, so I'm just
going to leave it as "normal".
Thanks.
