For now this kind of setup is the only that works on my machine.

No, LVDS and one HDMI.

Read note 1.

BTW: As far I know, AppleIntelFramebufferAzul has only two FB (Desktops) with two ports. Please correct me if I am wrong.

Data for 0xa26000a (the ig-platform-id your ioreg shows you're using...):
Code:
00000000: 0a00 260a 0003 0303 0000 0002 0000 3001  ..&...........0.
00000010: 0000 9000 0000 0060 9914 0000 9914 0000  .......`........
00000020: 0000 0000 0000 0000 0000 0800 0200 0000  ................
00000030: 1100 0000 0105 0900 0004 0000 8700 0000  ................
00000040: 0204 0a00 0004 0000 8700 0000 ff00 0000  ................

00000060: 0400 0000 0000 0000 0e00 0000 0000 0000  ................

There are 4 possible connectors in any ig-platform data, this one is limited to 3 due to:
0003 0303

And the three connectors within:
0000 0800 0200 0000 1100 0000 (LVDS)
0105 0900 0004 0000 8700 0000 (DP)
0204 0a00 0004 0000 8700 0000 (DP)

The truncated connector is:
ff00 0000 0100 0000 4000 0000

The idea would be to determine which DP/HDMI you need and patch it down to 2 connectors only...

That's what I'll try with my u430 anyway... we'll see what happens...

So how do I solve the problem. I am unable to boot into the system!! @RehabMan

You need to remove the old VoodooPS2Controller.kext, then install the new one.
You can remove it by using Terminal within the macOS installer (boot from a USB prepared according to my Clover laptop guide).

You should have updated it prior to updating the system... (perfect example of reading before acting).
