RELAXED_CAP_CHECK on T20
On a Thinkpad T20 using Debian unstable and a stock kernel.org kernel 2.6.11.6, building the kernel with CONFIG_X86_SPEEDSTEP_RELAXED_CAP_CHECK=y doesn't seem to show the error you're experiencing while loading speedstep-smi. So that means loading speedstep-smi module results to no error at all.

From the kernel config:
┌────────────────────── Relaxed speedstep capability checks ──────────────────────┠│ CONFIG_X86_SPEEDSTEP_RELAXED_CHECK: │ │ │ │ Don't perform all checks for a speedstep capable system which would │ │ normally be done. Some ancient or strange systems, though speedstep │ │ capable, don't always indicate that they are speedstep capable. This │ │ option lets the probing code bypass some of those checks if the │ │ parameter "relaxed_check=1" is passed to the module. │ │ │
this option only lets you use relaxed_check=1, it doesn't solve anything. this may mean that your model isn't affected at all, or that you have the described file in /etc/modprobe.d
ondemand t22
I would like to know if ondemand is possible on a t22. Also I'm wondering why cpu speed is only either 700mhz or 900mhz.
In /proc/acpi/processor/CPU/throttling there are 7 states defined, but changing them seem to does not do anything. Also cpudynd -acpi tells me there is no interface. I tried also to use acpi-cpufreq but it won't run because 'no such device'. How to use it?
Thx in advance, nusse.
no cpufreq interface found ?
I had a hard time to figure out that for cpufreq you also have to install (at least a subset of?) the modules
freq_table proc_intf
I used modconf where I found these modules listet under "kernel/drivers/cpufreq" tagged as "not installed".
