Ah, sorry. This special-casing / after-the-fact #error for 32-bit is
actually there in the RHEL-5 fork, and there I bumped only the x86_64
default (the 32-bit one is set to 32). When I looked at the upstream
source, I noticed only a single case (set to 128), and I figured
upstream either makes the 32/64 distinction by different means, or they
support 128 PCPUs on 32-bit too, and 128 being >> than 32, I thought 256
should be fine as well.
I was wrong, sorry for wasting your time.
