Good news - my WRAPs now pxeboot OpenBSD as expected! The culprit was
not pxeboot, but the etherboot PXE code 5.3.12 in BIOS 1.08 and 1.10,
as supplied by PCengines.
After building an etherboot 5.4.1 binary on rom-o-matic.org, merging
it into the BIOS and flashing the WRAPs, network boot of OpenB
Another OpenBSD on WRAP user wrote to me saying that pxeboot works.

PXE booting OpenBSD for the Soekris plattform which is very similar to
WRAP.
Both encouraged me to dig deeper:

Why is that posting interesting? That bug was fixed. I said that the

Doesn't really help you, but GENERIC runs just fine on Geode machines...
The posting

with pxe_call.

I found that the call to the assembler subroutine
pxe_call(PXENV_GET_CACHED_INFO);
never returns.
It looks like either there is something wrong with that call, or with
the PXE code from Etherboot.

Just tried it, but pxeboot does not continue to boot either.
tcpdump on the TFTP server reveals that the WRAP's PXE client actually
requests and loads the pxeboot file, but does not get that far where
it would request

Should we assume you have removed the CompactFlash device?
Have you tried bsd.rd ?
