Or is there some minimal PA-RISC hardware you could

The c8000, rp3410 and rp3440 are good choices to run PA-RISC linux. They can
still be found on ebay:

"2U rack" doesn't sound minimal. :-)
Sits nicely on top of an old file cabinet. Power is about $20/month.
Does make a bit of noise :-
I have been running the latest mainline kernel on C3700 for some years
already without issues. I guess it was supposed to be a "desktop"
machine, but it's still a bit too big and noisy, so for daily use I'm
still sticking with Ultra 5 (SPARC) machine..
It seems C8000s are now somewhat scarce and the price has risen. As
mentioned, the C3700 and C3750
will run the latest mainline kernel without problems. I tested the
latest update with a 64-bit SMP kernel
on my C3750. However, it's much harder to find memory to upgrade C37xx
machines and this is a
performance issue compared to the C8000.
The alternative patching in v4.20 should improve the performance of the
C3700 and C3750 when running
a SMP kernel as it eliminates locking in the TLB handler, etc.
