Fedora xen - Sep 2006 - vTPM on 2.6.17-1.2174_FC5

Hello,
       I''m working on a project which involves getting the vTPM set up
with Xen.  However while building the latest kernel rpm
(2.6.17-1.2174_FC5) I noticed that the vTPM front end driver is not
included.  I downloaded Xen from xensource and the vTPM front end driver
is included, however Xen 3.0.2 builds off of the 2.6.16 kernel which
doesn''t have TPM v1.2 support.  I thought about just patching the vTPM
front end driver into 2.6.17 but when I looked at Xen''s vTPM backend
driver code and the Fedora version, the Fedora version was much newer
and had a lot of changes.
 
So what''s the best thing to do?  Should I try to patch 1.2 TPM support
into 2.6.16 or try to bring the vTPM front end driver support into
2.6.17?  Is there a more recent FC5 kernel that has the vTPM front end
driver support?
 
Thanks,
Justin
