OpenBSD appears to be trying to access cp14 crn=0 crm=1 opc1=0 opc2=0. Implementing this as a no-op allows the image to boot.
I'm trying to track down what this is supposed to be -- it doesn't seem to be listed in the PXA27x docs.
(Previously we were lax about decoding and tended to print warnings and
no-op on accesses to nonexistent coprocessor registers; part of the
cleanup in the patches which introduced this regression was that we now
actually UNDEF in the guest on bad accesses, which is what hardware does
for unimplemented regs. This does mean that some cases of "we need to
implement this" that were previously slipping under the radar now need
to be explicitly catered for.)

Ah, found the problem -- it looks like I accidentally transposed the
crm/crn values for all the perf registers in commit dc2a9045c, in the
process of converting from switch statements to the table
representation, and my test Linux image obviously doesn't prod these
registers. I'll send out a patch...

Fixed by this patch http://patchwork.ozlabs.org/patch/217673/ which
hopefully will make it into 1.4.
