Rpi4 Install issues (Required for my touchscreen to work)

I have had no luck getting my ElecLab touchscreen working in bookworm (no display output).
Have it fuctioning on bullseye.

I was able to get the prempt_RT kernel installed successfully,
```6.6.50-rt42-v8+ #1 SMP PREEMPT_RT```

I am hitting a brick wall with the dependencies for linuxcnc_uspace.
libc6 seems to be the largest issue, as I can't get it to install the local deb package (keeps saying the version from apt is current, and installed).

Here is my Githug issue for the touchscreen:

UPDATE:
building the 6.12 rpi kernel (patched with RT) on bookworm, has the display and touchscreen working correctly.
But, now wifi is broken

I'm going to look through the notes and try another kernel that is a bit closer to 6.6
