2.5 TODO/STATUS

o   All drivers
    - enable support for dynamic switching, where possible

o   Longhaul
    - Early Cyrix 3 support still needs finishing.
    - One odd report where a C3 only had 3 speed settings,
      still need to decode info and find out if this is accurate.
    - the routine to pick a voltage for a given speed needs improving.

o   Speedstep
    - integrate speedstep v.1 support (db)
