Title:
  Toshiba Libretto/Transmeta CPU based machine runs at 50% cpu
  performance all the time.

Status in “toshset” package in Ubuntu:
  Expired

Bug description:
  Hi.

    This issue has stayed with me into Dapper (which I am now testing).
  I thought I'd let you know about it now before Dapper goes to final
  build.

  Essentially, I've tried to get in touch with the author of toshset to
  no avail, but the issue seems to be with the toshiba_acpi module in
  the kernel since breezy.

  Sorry about the length of this post, but most of it is debugging that would just get asked of me anyway.
   
  The laptop runs at around 400MHz, but it's supposed to be 800MHz. The toshset has a feature for fast or slow mode, depending upon how long you want the batteries to last. Problem is, this mode can't be set because it can't hook it's necessary (proc?) interface.
   
   Here is a bit of debugging (take note especially the following 2 lines 
  error when querying feature: CPU speed: FAILURE
  error when querying feature: CPU sleep mode: FAILURE).

  toshset -v -q gives:
   
  machine id: 0xfc8b    BIOS version: 1.40    SCI version: 200.196
  toshset version: 1.70                  Toshiba Model: Libretto L5

  ...

   I note that /proc/acpi/toshiba contains only entries for fan, keys, lcd, version and video, probably explaining the above output.
   
  I attempt to set it to 'fast' mode with the -cpu flag but I get the following error:
   
   
  % toshset -cpu 1 -v
  SciFeature:action: error setting CPU speed
          SciSet returned: FAILURE

  This is the end of my kernel audit output when I insert toshiba_acpi manually (modprobe):
   
  [4297632.326000] Toshiba System Managment Mode driver v1.11 26/9/2001
  [4299557.707000] Toshiba System Managment Mode driver v1.11 26/9/2001

  [4299640.786000] toshiba_acpi: Toshiba Laptop ACPI Extras version 0.19a-dev
  [4299640.788000] toshiba_acpi:     HCI method: \_SB_.VALD.GHCI
  [4299640.930000] toshiba_acpi: Toshiba hotkeys are sent as ACPI events

  [4299641.302000] toshiba_acpi: Dropped 0 keys from the queue on startup

  I know the machine is working fine speedwise because when it's in
  Windows the speed settings are set for performance, and it definitely
  feels about double the speed.

  I am not the only Toshiba Libretto L series user running ubuntu out
  there, so i'm sure it's worth looking at this for a fix/update, Ubuntu
  is unusable on it now at Transmeta ~400MHz (feels like Intel 200MHz!).
