The problem:
- Thinkpad module does not create /dev/thinkpad.
- I have read that this problems is related with udev rules.
- Some programs like tpctl doesnot complian but configure-thinkpad does.
- Suposily there is a fix but is temporary for every reboot, and some times does not work.(This fix is from the FC(RH) people)
Code:
  #mkdir --mode=755 /dev/thinkpad
  #mknod --mode=664 /dev/thinkpad/thinkpad c 10 170
  #chown root:thinkpad /dev/thinkpad/thinkpad
- Also added some alias (Dont know what the Do :( )
Code:
 Modules.d/Thinkpad
# modules.d configuration file for THINKPAD
# For more information please read:
#    README

options thinkpad enable_smapi=1 enable_superio=0 enable_rtcmosram=0 enable_thinkpadpm=0

alias char-major-10-170 thinkpad
alias /dev/thinkpad thinkpad
alias /dev/thinkpad/thinkpad thinkpad
alias /dev/thinkpad/smapi smapi
alias /dev/thinkpad/superio
alias /dev/thinkpad/rtcmosram  rtcmosram
alias /dev/thinkpad/thinkpadpm thinkpadpm

# Configurable module parameters
# ------------------------------
# enable_smapi:   Enable/disable (1/0) use of the smapi module
# enable_superio:   Enable/disable (1/0) use of the superio module
# enable_rtcmosram:   Enable/disable (1/0) use of the rtcmosram module
# enable_thinkpadpm:   Enable/disable (1/0) use of the thinkpadpm module (obsolete)
- Also some peole have problem compiling module (Theres also another link to this[/code].) (Solved by reinstaling gentoo in my pc.)

By gues testing
- Found that configure-thinkpad uses the old thinkpadpm module.
- By putting this settings on your /etc/modules.d/thinkpad
Code:
 /etc/modules.d/thinkpad
# modules.d configuration file for THINKPAD
# For more information please read:
#    README

options thinkpad enable_smapi=1 enable_superio=1 enable_rtcmosram=1 enable_thinkpadpm=1

alias char-major-10-170 thinkpad
alias /dev/thinkpad thinkpad
alias /dev/thinkpad/thinkpad thinkpad
alias /dev/thinkpad/smapi smapi
alias /dev/thinkpad/superio
alias /dev/thinkpad/rtcmosram  rtcmosram
alias /dev/thinkpad/thinkpadpm thinkpadpm

# Configurable module parameters
# ------------------------------
# enable_smapi:   Enable/disable (1/0) use of the smapi module
# enable_superio:   Enable/disable (1/0) use of the superio module
# enable_rtcmosram:   Enable/disable (1/0) use of the rtcmosram module
# enable_thinkpadpm:   Enable/disable (1/0) use of the thinkpadpm module (obsolete)

- This will solve the problem forn a lot of ibm thinkpad users.
- It know creates /dev/thinkpad and /dev/thinkpad but suspend to ram in configure thinkpad gives error system is invalid
Any help is apreciated
