Test booted this patch series on the problematic t3400, seems to work
fine. dmesg attached to bug 15744.
Thanks for testing (again). I'm not confident that this series is
going to be successful, so I started looking for other approaches.
I can't reproduce the exact problem you're seeing, but in my
kludged-up attempt, the patch below is enough to keep us from
assigning the space below 1MB to a device.
Would you guys (Andy & Andy, what a coincidence :-)) mind giving
it a try? This is intended to work on top of current upstream,
with no other patches required.

Good news- that solved it. I tried Yinghai's patches saturday to no
avail (sorry it took me so long to get back to you, I was about 5 bios
revisions behind on this machine and wanted to update it before I
tried any more tests).
