Did some tests.
Results so far: booting ofwboot and kernel from HFS+ is indeed busted
4.1 ofwboot + 5.0 bsd.rd DOES boot
4.2 - 5.0 ofwboot do not work
Loading ofwboot itself does work, only loading the kernel fails.
A (theoretical) workaround is to use the 4.1 ofwboot + 5.0 bsd.rd,
install and then copy the 5.0 ofwboot to the HFS+ volume. The moment
an OpenBSD partition exists, ofwboot (itself loaded from HFS+) will
load the kernel from that OpenBSD partition. That's the reason this
bug has existed for so long.
Lemme try the ofwboot 4.1 workaround... [some time passes]...
Indeed, that works! The moment an OpenBSD partition exists ofwboot
(both 4.1 and 5.0) will load a kernel from there.
