   TODO items for improving NetBSD/xen
   ===================================
   
   * Package Xen 4.4.
   * Get PCI passthrough working on Xen 4.2 (or 4.4).
   * Get pvgrub into pkgsrc, either via xentools or separately.
   * grub
     * Add support to pkgsrc grub2 for UFS2 and arbitrary
       fragsize/blocksize (UFS2 support may be present; the point is to
       make it so that with any UFS1/UFS2 filesystem setup that works
       with NetBSD grub will also work).
     * Push patches upstream.
     * Get UFS2 patches into pvgrub.
   * Add support for PV ops to a version of /boot, and make it usable as
     a kernel in Xen, similar to pvgrub.
