If you're talking about X, try to emerge HAL daemon, it's now necessary to work your input devices correctly.
If you're talking about console, try to look trough output of "dmesg | grep 'usb' " there must be something about your USB HID keyboard, may be some errors about it. Also look through "lsusb", is your keyboard mentioned here?

Hi,

I doubt there is hardware problem in keyboard itself,
because it works in bios as well as on lilo-screen, and
it even works when I attach to PS2-port using adapter.

In kernel-config (2.6.22) Support for Host-side USB is
activated, EHCI/OHCI/UHCI HCD support, USB mass storage
support, and USB Human Interface Devide (full HID)
in Generic HID Support.

I can select kernel on lilo screen, but after boot-up
process is finished, my keyboard is dead. I tried to pull
it out, and reconnect, no difference. What can I do more?

Is this on the console or in X?
X has recently changed the keyboard and mouse configuration to use HAL
