I actually have ccache so I hope it'll be little faster this time. Anyway, I'd better change the voltage values right now before I'll apply the patch…
And when I am actually dealing with that…why is there only seven steps? Pentium M 745 is capable of doing only 100 MHz steps, thats thirteen actually (or twelve, 700 MHz is not used, don't know why).
OK here come the dificulties. I guess number of steps is defined here:
.index = (((mhz)/100) << 8) | ((mva - 700) / 16)
I changed it to << 12 but still the patch fails around line 190.

Any idea how to set more frequency steps? The processors is capable of that, I used it under XP (RM Clock). I am sure the problem is only with the syntax :-)

I tried to apply original patch and than add the lines directly into speedstep-centrino.c in kernell source tarball. I compiled the kernel, installed, everythink works fine except this module. I still get:

FATAL: Error inserting speedstep_centrino (/lib/modules/2.6.36-pentium-m/kernel/arch/x86/kernel/cpu/cpufreq/speedstep-centrino.ko): No such device

Well I HAVE Dothan 745A so where the hell is the problem?
