ok, I found a workaround for the 600Mhz problem with the telephone app that works for me.
my workaround basically ignores all requests to set 600Mhz in the kernel.
if you want 600Mhz you would specify 599MHz or something smaller.
as soon as the same works for the minimum (125MHz) I'm going to upload a new kernel...

I did flash with Lehto previously, prior to using the Titan's kernel version. Lehto's version does not work for me running @900 Mhz stock version. Some of video display freezed after using for a while and got over heated, and I would like to run at 900Mhz. Fortunately, Titan's version works for my device, but facing the reset problem.

I understand that not all devices are equal or the same, specially different chip set. That why I need help from Titan.

(It is not used for graphics - OMAP 3430 has TWO graphic accelerators besides DSP).

EDIT: it can be used for MPEG decoding during video playback.
It means it decodes video off websites quicker.. thus, better video with overclocked ones ??

I think the extra-decoders don't use DSP. But for officially supported codecs (which may use DSP) Nokia does a good job anywhere.

good news! my workaround works!
by default the kernels sets the range to [250,600MHz] (even if pmconfig contains 125000/600000).
To set the minimum to 125MHz use 124000, for a maximum of 600MHz use 599000, otherwise use the real frequencies.
min=125000 and max=600000 are ignored by the kernel.
EDIT: 125MHz lower limit does not work after phone calls. don't use the 125MHz!

Installation:
Code:
wget http://maemory.com/N900/overclock/kernel-maemo_2.6.28-maemo20_armel.deb
wget http://maemory.com/N900/overclock/kernel-modules-maemo_2.6.28-maemo20_armel.deb
wget http://maemory.com/N900/overclock/kernel-flasher-maemo_2.6.28-maemo20_armel.deb
dpkg -i kernel-m*
dpkg -i kernel-f*
halt

It has a big sense to test

- voice calls quality (including VoIP)
- bluetough headsets with voice calls.

Because that change (600MHz setup) was done after PR1.0 and I suspect a reason lies in fixing some bug.

note that with the new workaround the phone app locks the device to
[600,your limit] instead of [600,600] and during the call to [250,your limit] instead of [250,600].

Because titan's kernel isn't only about overclocking and pack a lot more useful features.

@titan,
Is there any chance that I can update through app manager? I did check app manager and your new update (work-around version) is not there yet. Thanks.

I'm waiting for some feedback whether the workaround works for other people.
then I'd upload a new version to extras-testing.
