I would boot into a non-graphical target with both kernels, capture the dmesg output and compare it for signs of differences in memory layout setup.
I will do that tomorrow, when the two monitors are attached again. Apart from some screen flickers (only in the first hour after boot???) the laptop seems to run fine with kernel 5.2 and no external monitor / on battery power.
