applied the mem limit to 768MB in uboot as a workaround but if I can

I fear that issue will never get resolved. Andrew Lunn, who was the
most active Kirkwood kernel maintainer at that time, looked into it
and couldn't figure out what was going on. In theory, we could check
what he wrote about it at that time (or ask what he remembers) and
report it upstream with the hope that someone will investigate but I'm
not sure who that someone would be.
(Maybe Arnd Bergmann but I suspect his plate is full already.)
It's particularly annoying because this is a regression and the Linux
people care a lot about fixing regressions, but I think at this point
there aren't many Kirkwood users left anyway...
I forgot what the problem was, but it sounds like the differencePS: is there any way I can help with debugging the 1GB RAM issue? I

between CONFIG_VMSPLIT_3G and CONFIG_VMSPLIT_3G_OPT in the kernel.
Ideally you'd want to use CONFIG_VMSPLIT_3G_OPT in a kernel for
a system with 1GB of contiguous RAM, but I don't know if the
problem here was caused by picking this or not picking this.

I have continued to run with 768MB which is enough for my use cases, and
with the Debian 11 (after the flash partition restructuring script and dist-ugprade) the system has been rock solid.
Now of course I would be curious whether anyone has tried upgrading any Kirkwood devices to Debian 12, but bullseye has luckily plenty of
support remaining.
