Yes, I used these patches on top of 2.6.33-rc2 and 2.6.33-rc2-next-20100101
for an ethernet chip at 0xd:1000:0000 on a Au1250 board.

I don't remember seeing oopses while I was figuring out how to get
36-bit I/O working.  arch/x86 and arch/powerpc have been supporting
32-bit processors with 64-bit physical addresses for a long time,
so I would expect the generic resource management code to be reliable.
There are other changes in my tree, but I can't think of anything
which might affect this.  Let me know if I can help further.
