changelog:
#17 Had included mismatched wifi module in #16 and fixed install zip to handle ext4 /system partitions also.

#18
Removed sysfs tuneables for smartass
Fixed smartass gov that didn't scale properly. Just like interactive gov that I didn't include smartass has random lockups at freqs above 1612mhz especially @ 1804mhz.
Added smartassV2 this newer revision of smartass does not have the lockups at highest freq like original smartass does.

#21 This one is for sense 2.3.4+ only usb mounting is fixed for 2.3.4+

Thanks , can you advise me the right voltage to increase my battery life with it ?
I will give it a try
EDIT : i got connection closed but the server , can you please upload it in megaupload ?

Its already undervolted. Power users can adjust it even more via sysfs.

Stock voltages were:
245760 1000 100mv undervolt on mine
368640 1050 125mv undervolt on mine
768000 1100 100mv undervolt on mine
1024000 1200 150mv undervolt on mine


1305mhz is running at 1175mv which a 25mv undervolt from the stock voltage at 1024mhz.

How does greased lightning governor work? And ondemandx. I've heard of the others

So far so good. Initially had a lockup in SetCPU but after battery pull all is good. Hope the undervolting adds a little to my already awesome battery life.

    Governors explained!

    This kernel has an astounding number of scaling governors. Is there a FAQ or README summarizing the subtle nuances of each governor?

    I realized this was such a n00b question that nobody would answer, so I spent an hour or so researching it. Corrections welcome:

    Governors:
    performance - Always runs at highest speed.
    powersave - Always runs at lowest speed.
    ondemand - Default. Raise/Lower CPU speed based on load.
    conservative - Similar to ondemand, but ramps up CPU speed at a slower rate.
    interactive* - Scales the CPU frequency up when coming out of idle. If the CPU is 100% busy from exiting idle when the timer fires, assumes CPU is underpowered and ramps to highest speed.

    smartass - Like interactive. Runs at higher speeds based on load. Locks processor at lower speed during screen off.
    superbad - More aggressive smartass hybrid. Prefers higher speeds.
    greaselightning - Identical to superbad, but ramps up with less load. More responsive.
    scary - Hybrid of smartass and conservative. Like conservative with a screen off state.

    minmax - The "old" smartass.
    ondemandX - Similar to ondemand, but set to ramp up for input events too.

    *interactive is not supported by this kernel, but is included for reference.
