Thanks Jake Lo!
You are quite right, its a Alps V7 trackpad, if Linux is right.
Never thought I would miss trackpoint or upper mouse buttons, but I became used to them, seemingly.
As for the SD card reader, many PCI card readers may work some day, if the JMicron software could be patched accordingly.
Fun fact, I have such a card reader with my T420 and its working with Mojave - even though the installer package is for Lion or lower.

What do you think about the non working LAN?
Is there anything I could try?
Not that I would use LAN much with a notebook.
One other thing:
I´m getting KP on restart/shutdown with 10.13.6, should I better update Clover from r4910?
