If the network adapter is supported by Linux 2.6.29, it should be
possible to get it working with the DDE userspace driver framework. This
is a bit non-trivial to set up though...

SATA is more of a problem.

Also, first thing you should use the installer CD to test whether Mach
even boots on your machine... Otherwise there is obviously no chance of
running the Hurd natively :-)

Yes, a VM can be used to work around the ethernet problem. It can also
be used to work around the SATA problem for the system disk.

However, you still need a way to access the actual burner... I don't
really know, but I rather doubt that any VM solution actually exposes
the host system's burner to the guest system as an ATAPI device
connected to a virtual PATA controller...

If your machine supports IO virtualisation (IIRC AMD simply calls that
IOMMU), you *might* be able to use a real PATA burner, and give the
guest system direct access to the the PATA controller it is connected
to. Don't know though whether this really works...
