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. Pascal
