Hi,
Can you let us know if the PowerMac11,2 has 4 DIMM slots or more? If it
is 4, then that means a DIMM can be 4 GB in size, which means my second
update patch may fail and a 16 GB memory PowerMac may get the same 0 MB
that my PowerMac7,3 is getting. The fix isn't trivial for that though
and should probably be a second patch to make OF_* (openfirmware)
routines be able to parse 64 bit entities), since a DIMM with 4 GB would
wrap over again on an unsigned int and represent 0.
A dmesg would rock.
Regards,

According to wikipedia only the PowerMac11,2 supports up to 16 GB the rest
are all maximum 4GB, and I don't think the PowerMac11,2 is supported.

I'm not sure what the correct fix for this is but I wanted to set the
record straight. The PowerMac11,2 is supported but does have some DMA
issues with the SATA controller that can result in timeouts. All
OpenBSD/macppc machines are 32-bit or run in 32-bit mode like the
PowerMac G5. I believe that is why there are issues with large amounts
of memory. I have a PowerMac11,2 that has more than 8GB of memory (I
can't remember the exact amount) and it only uses 2GB as well under
OpenBSD. I also ran into some radeon(4) issues which I documented in
some older threads. I have not had time to get back to working on
anything further with my PowerMac G5 units but the model you have should
work reasonably well except for possible SATA issues.
