Have you tried CONFIG_IDEAPAD_LAPTOP? And if it doesn't help, could you please provide lsinput from systemrescuecd?

Thank you for suggestions :)
Unfortunately CONFIG_IDEAPAD_LAPTOP did not help.

Turns out systemresquecd uses Archlinux now, a pity.. and they don't have input-utils.
Still I have got relevant content of /proc/bus/input/devices:

Code:
I: Bus=0018 Vendor=06cb Product=7f27 Version=0100
N: Name="SYNA2B46:00 06CB:7F27 Touchpad"
P: Phys=i2c-SYNA2B46:00
S: Sysfs=/devices/pci0000:00/0000:00:15.1/i2c_designware.1/i2c-23/i2c-SYNA2B46:00/0018:06CB:7F27.0005/input/input29
U: Uniq=
H: Handlers=event18 mouse1
B: PROP=5
B: EV=1b
B: KEY=e520 10000 0 0 0 0
B: ABS=2e0800000000003
B: MSC=20

It is present in livecd environment and missing in gentoo system

I already tried this, with no success
Code:

CONFIG_I2C_DESIGNWARE_CORE=y
CONFIG_I2C_DESIGNWARE_PLATFORM=y
CONFIG_I2C_DESIGNWARE_SLAVE=y
CONFIG_I2C_DESIGNWARE_PCI=y
CONFIG_MOUSE_PS2_SYNAPTICS=y
CONFIG_MOUSE_PS2_SYNAPTICS_SMBUS=y
CONFIG_MOUSE_SYNAPTICS_I2C=y
CONFIG_MOUSE_SYNAPTICS_USB=y
