NOTES:
  - Framebuffer-based install is not available in this release due to the
    kernel version used.  DMA API changes were in progress when this version
    was released, and additional changes to make gbefb work again were not
    added until later kernel versions.

  - R1x000 CPUs are NOT supported in Linux on these systems due to the nature
    of "speculative execution" on these systems.
