Description of problem:
I figured this will probably be a good thing to have, so I'll open up the BZ
myself.  It would be very nice to have pci passthrough support available for
RHEL4 PV.  The implementation shouldn't be all that complex; we have most of the
infrastructure already, it's just a matter of getting the code from RHEL-5 and
hacking it up to work with RHEL-4, and then doing the associated testing. 
Hopefully we can get this into 4.6.

Preliminary RHEL-4 PV pcifront patch

This is a very preliminary patch against 2.6.9-54 that adds pcifront support to
PV.  It has only been compile and boot tested on i686; I'll need to do the same
for x86_64, and then, of course, test :).

Preliminary .config file for RHEL-4 pcifront support

This is a .config file for 2.6.9-54 that adds the minimal config options needed
to enable pcifront support for PV.  Note that none of the usual drivers are
enabled; to really make this useful, we will probably have to enable most of
the normal PCI drivers that a RHEL-4 kernel has.

Closing this out until somebody asks for this feature in RHEL-4.
