Search for PS2 drivers specifically for ALPS.

You simply haven't found a ps2 driver appropriate for your hardware.

You must not be using a ps2 driver written for your trackpad. There is no native support for ps2 devices provided by Apple.

Do i need to delete old ps2 kexts from system before i install new one?

And, when I'm booting i always need to type in a boot flag /System/Library/Kernels/kernel
What should i do that i don't need to type this anymore?

Definitely. It is a bad idea to have multiple kexts installed for a single device.

And, when I'm booting i always need to type in a boot flag /System/Library/Kernels/kernel
What should i do that i don't need to type this anymore?

Check your org.chameleon.Boot.plist and make sure it DOES NOT have a "Kernel" specification.

You can clearly see your org.chameleon.Boot.plist is incorrect for Yosemite. There is no 'mach_kernel' in Yosemite.
