Hi,
I have been trying to get ACPI working on the IBM Thinkpad T23.  I am
using linux kernel 2.4.20 patched to 2.4.21-pre5 and also the
corresponding acpi patch.  I have applied the ECDT patch so that the OS
now replaces the ECDT during bootup. 
Also, I commented out the        "if (ec_ecdt && ec_ecdt->uid == uid)
{...}"   block in acpi_ec_add() of ec.c.
All this has got me to a stage where I get all the directories in
/proc/acpi.  However, the fan subdirectory is empty and the processor
performance gives out:
 
*P0 :  0 MHz  0mW, 500uS
P1  :  0 MHz, 0mW, 500uS
 
although the processor supports speedstep.  Any ideas what might have
gone wrong??
 
Any help appreciated,
Jayan.

I hope you file this issue on bugzilla.kernel.org.
Also you should tell us how to reproduce the problem.
 
Thanks,
Luming
