Use at your own risk
I take no responsibility for any demage, which this kernel can cause


Key kernel features
- OC MAX to 1.53GHz
- undervolted
- Interactive, powersave, conservative, ondemand, performance governor
- BFQ IO scheduler
- SLQB allocator
- EXT4 support
- TUN module
- CIFS module
- snq- CPU Vdd levels
- change frequency on-the-fly



I bought Motorola Atrix 4G


Changelog v2.3 - for real enthusiasts
- RockPlayer lag fixed
- adb developer mode fixed
- added BFQ IO sched as default

How to change any frequency above 1017600Hz on-the-fly
Code:
echo 'c1536000 1593600 1325' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
"c" means CHANGE
"1536000" old frequency
"1593600" new frequency (unlimited)
"1325" voltage (limited to 1500mV)

How to set max frequency on-the-fly
Code:
echo 'm1593600 1350' > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
"m" means max frequency
1593600 is max frequency (no limitation)
1350 is voltage for this frequency (maximum is limited to 1500mV)

{ 1017600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1113600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1209600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
{ 1305600, PLL_2, 3, 0, 192000, 1200, VDD_RAW(1200) },
