mb/lenovo/{t60,r60}: Add ThinkPad R60 support as variant board
- This port should be Reclaim Your Freedom compliant (not certified yet). - Untested on boards with external Radeon graphics adapter. - Some columns on the left-most side of display are completely black on 1400x1050 IPS display[1]. Display works fine on Linux. I don't know why it appears like that. So far it has been observed only with native graphics initialization. - Only GRUB2 and SeaBIOS payloads tested for now. - 2504 docking station USB doesn't work under Linux. Can detect pendrive in GRUB2 payload. - Sometimes it takes 20s of "pretending it's powered off" to run coreboot code. Issue is payload agnostic. Probably caused by missing one capacitor on my unit.
