64x128 with 2053 - help needed

The question first: Did somebody succeed to run panels with ICN2053 on raspi/hzeller library?

In my latest project I have a pile of nice 128x64 P2.5 HUB75E Panels to play with. I try to run it with rpi4 and adafruit bonnet.
The Chips are 48 x SJ27707 - very different and the number of chips is quite low. I was assuming it must be some mutation of 6126 chip.
I found (after a while) Issue #1070
#446 and pixelmatix.

Progress so far:
the “Swap lines” trick in the library as per #466 got me erratic light on the raspi
The ESP32 code of [SebiTimeWaster](SebiTimeWaster/ICN2053_ESP32_LedWall: An Arduino implementation to drive ICN2053 based LED wall segments running on the ESP32 platform (github.com))
has worked for a maximum of 64x220 nicely.

Those chips are not supported, they work very differently, see

I’d love to see them work, but they require different code. Please update the bug with progress if you make any
