Hello,
I've been finally able to install OpenBSD accidentally, I powered on the machine without the screen on and for some reason the lenovo used a very low resolution like 640x480. That's exactly what machine gop shown (and the only available resolution).
Maybe the machine did use a degraded resolution due to absence of video signal? dunno. But now I can enjoy OpenBSD on this machine. It works perfectly.
