Sooo, I think I've bricked my PW4 for good:

As I hate Kindle Feedback item in my library I've removed its creation from /var/local/mkk/bridge.sh.
Everything went fine, except PRE_GM_<blah> was still created every reboot.

That's when I've found /var/local/system/fixup script.

I've again modified it to skip PRE_GM flag setting, but I've made a typo somewhere ;(
Now the dearest device is in a bootloop, without any chance to even inject emergency.sh...

EDIT:
Fixed!

Being away from my workshop I had only essential toolbox with me. Unfortunately no UART converters there, but I found some stray Pi Zero, hooked it to Kindle's HW serial, entered kernel recovery mode...
There I was able to mount fat partition and upload emergency.sh with some recoveries.
I'm up and running again

kindle dx usbnetwork r17925 doesn't work, legacy hacks version (linked above) does

Just tried jailbreak and usbnetwork from the above list and the usbnetwork bin for dxg doesn't get recognized by the kindle menus where the legacy hacks version linked above does get recognized and installs properly it seems.

Sorry. This is the second time I didn't notice

Please note that all these packages can only be installed through MRPI (and I strongly recommend using a recent version ), *even* on legacy (<= K4) devices.
So I will restart with jailbreak, mkk, kual, mrpi and then usbnetwork from here.

fbgrab

Just reporting that using the fbgrab tool bundled in a recent usbnet for the K3 (kindle-usbnetwork-0.57.N-r17925) I get

Code:
[root@kindle us]# fbgrab fbgrab.png
fbgrab: /mnt/us/linkss/lib/libz.so.1: version `ZLIB_1.2.9' not found (required by /mnt/us/usbnet/lib/libpng16.so.16)
[root@kindle us]#
Probably to be expected on a 10 year old device...

@PoP: You'll need to update the ScreenSavers hack, too.

(The rpath entries are searched in order, and libpng searches for zlib in linkss first. If it finds it, it stops looking, even if it's too old).

^ Of course.

I (blindly ) did install a recent screen saver but checking the mrinstaller.log I found
Code:
Not enough space left to process ss 0.47.N U, skipping . . . :(
Freed some space, reinstalled and all is good now:

Code:
[root@kindle root]# cd /mnt/us
[root@kindle us]# fbgrab fbgrab.png
Skipping 0 bytes
Resolution: 600x800 @ depth 4
Converting to Gray8
Allocating 480000 bytes for conversion buffer
Now writing PNG file (compression 4)
[root@kindle us]#
Thanks.
