T60 need to diagnose

Hi, I recently restored my Thinkpad T60 (14), and now I replaced my mobo with ATI crap, with Intel one. I flashed it with Libreboot. But computer won't to connect to the internet, lan, wifi, usb wifi. I tested with 3 internal PCIe Atheros cards, and with 2 routers, and one usb wifi atheros. It detects everything, any connection, but when it connects, instantly it disconnects. I tryed to connect from computer directly to router, and nothing works. No kernel panics, no crashes. I upgraded to the latest beta Libreboot release, same thing, I downgraded to previous stable Libreboot versions, and the same thing. "ifconfig -a" works fine, it is all right with MAC adresses. I tryed with live Trisquel and live Mint (usb and CD), and same thing, tryed to install Trisquel and it fails at middle of install. "dmesg | grep fail" says:

[drm] failed to find vbios tables
acpi pcc probe failed

when booting GNU/Linux, kernel says: i915 invalid ROM contents.

LAN hardware is Intel 82573l.

So, I need to know what fails, for fix it, I have no problem to desolder chips and replace.
