here are KP49 .debs with SR (hopefully) working for range 125-900 MHz. I would appreciate if brave souls test it and comment.
There is an additional value in /sys/power called sr_vdd1_voltage. It contains current OPP voltage as calculated by SR. One can compare it and report what are the differences between what SR thinks is optimal and what he thinks is for a particular frequency. I need that info to check if current SR settings in kernel are optimal.
Any additional feedback is welcome too.
*edit* , i see on the kp49 from 1st november that no bridgedriver is supplied in kernel-power-modules_2.6.28-10power49_armel.deb so is this new addition needed for my 720p ?

@Estel
supl.google.com works. I guess Elop is really trying to kill the N900 by taking them away under warranty and now canceling a-gps server. Good thing it's not KP fault

Otherwise 33 for 500 is a little high, I agree, but not much to be done here, some devices pretend they can run 500/30, but actually cannot, that is why there is a little voltage boost for 500.
500/360=33
550/520=36
600/520=39
I tested also 550 at 36, immediate error, doesn't even think about it. 39 for 600 is stable as I said in the post above.
33 for 500 seems pretty high, though.
In short, don't try some exotic frequency profiles with SR enabled, it won't work. Use dsp profile and if it is not stable re videos, move DSP overclocking to higher frequencies(look at knobby's posts).
Anyway thanks for your help testing SR.

BTW, I don't use SR, just tested for you.
Oh....and you're welcome!

These are sr_vdd1_voltage values:
250 MHz sr_vdd1_voltage 23-34
500 MHz sr_vdd1_voltage 36-48
550 MHz sr_vdd1_voltage 35-54
600 MHz sr_vdd1_voltage 38-60
720 MHz sr_vdd1_voltage 52-60
805 MHz sr_vdd1_voltage 48-60
850 MHz sr_vdd1_voltage 52-60
900 MHz sr_vdd1_voltage 53-60
How can I check what voltage is best to use, since current OPP voltage as calculated by SR is lower than set by dsp profile?
Thanks in advance...

BTW are you sure you wrote correct values for 500(36) and 720(52)?

Turning display on from side switch at 125M with low voltages cause reboot (32wd_to).
Voltages below 20 seems to be problematic when device is waked with side switch. Sometimes it wake -up OK, but time to time nothing happens on screen and 32k WD kick-in causing reboot. Also if side switch is pulled several times (display on & off) then this is also causing reboot.
Otherwise 125:12,90 is OK if you won't let it go sleep/deep-sleep or what it is doing when display is off.
EDIT: Verified with 2 devices. No matter if SR is enable or not.

All times are GMT. The time now is 08:33.
550/520=36
600/520=39
I tested also 550 at 36, immediate error, doesn't even think about it. 39 for 600 is stable as I said in the post above.
33 for 500 seems pretty high, though.
