I don't know if there are pre-packaged kernels for lenny with pcifront driver.

Links to kernel sources that have the pcifront driver:

        - http://xenbits.xen.org/linux-2.6.18-xen.hg
        - pv_ops xen.git xen/stable 2.6.32.9 and xen/master 2.6.31.6
          (See: http://wiki.xensource.com/xenwiki/XenParavirtOps)
        - Kernels with the forward-ported Novell/opensuse Xen patches (2.6.29, 
2.6.31, 2.6.33)
          (See: http://wiki.xensource.com/xenwiki/XenDom0Kernels)
