    Actually rebooting is not the right way. It should halt and then boot (cold reboot).

    overclocking is summarized at http://wiki.maemo.org/Overclocking

    there is a new version of the kernel on http://talk.maemo.org/showpost.php?p...postcount=1890
    that is even safer than the stock kernel.

    This causes the warning that you might seen with system firmware upgrade.
    You have a prompt that your system will be upgraded and rebooted before accepting package installation and you are advised to do backup before. It might actually be good idea before kernel upgrade.

    Not sure what your scope for "optional" is, but I'm talking about "optional [for installation of the package]". Just like one doesn't have to run a new game immediately after installing it, one does not need to *use* the new kernel immediately after it's been installed. What if you want to change installed kernel scripts / inspect modules / change the blacklists / etc. after the kernel's been installed before it's being booted?

    Clearly a reboot is required to *use* the new kernel, but this should not be forced on the user that has just installed the kernel unless it is always necessary for the *installation* process. "not necessary for the *installation* process" is what I meant by "optional".

    Compulsory reboots are clearly not required to complete the installation of the kernel packages. So don't force it on the user.

    Does the undervolting kernel here include the fix for phone calls reverting frequency back to 600?

    EDIT: I just went to update my device and saw there is already a version 20 of your kernel in the official repos. There are two version 20's listed on your site, one with undervolting and one without. Which version is in the repo?

    EDIT2: Just booted the undervolted kernel that I linked to above, and can confirm that the issue with phone app reverting frequency is still present. I booted into 800Mhz, and after a call to my voicemail I'm back at 600Mhz

    In addition I recommend you to run this commands and test it again:

    echo "1" > /sys/devices/system/cpu/cpu0/cpufreq/ondemand/ignore_nice_load

    renice 1 `cat /syspart/applications/standby/background/tasks`
    renice 1 `ps | grep modest | cut -c1-5`

    It should save you a lot of battery over standby. I have increase more then 50%.

    (Note: modest renice would work until you call e-mail GUI, after that it reverts back. I am working on it)

    Can this be placed in /etc/pmconfig?
