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 =3D=3D 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.
