x86_32 (PAE)
    1. SLES 9 SP2, FC3, and RHEL 4 IBM xSeries 305, and
       ThinkCentre
         * Machines boot up now
         * Ran LTP on dom0 without swiotlb=force and machine stayed up
    2. Boots on RHEL 4, SLES 9 SP2 and FC3.

        * Booted Dom0 using swiotlb=force
        * Ran LTP on both Dom0 and DomU

    3. ISSUES:
            1. DomU boot crashes Dom0, Bugzilla #168
                    1. Workaround: use swiotlb=force as a kernel
                       parameter when booting Dom0
                    2. DomU boots up normally if using swiotlb=force
            2. X server will not come up on Dom0 on a FC3 box when Xen
               built with PAE 'on', Bugzilla #137
            3. Networking issue on FC3 when Xen built with PAE, Bugzilla 
#173         
               * DomU unable to get dhcp address
               * tcpdump shows lots of networking activity being 'heard'
               * ping from external box shows corrupt packets
               * DomU has no trouble getting IP address when Xen built 
non-PAE, however

x86_64
    1. SLES 9 SP2 and FC4 on IBM HS20 Blades
    2. Xen build break on both distros
    3. ISSUES:

        * Bugzilla #169 - x86_64 - Unable to handle kernel paging
          request at ffff8000003e0000 RIP:
          <ffffffff8015d16c>{unmap_vmas+1084}
