Thanks for testing, but I'd like to get a handle on what's going on first.

First, I'm pretty sure when driver is loaded things work OK on all systems.
When driver is not loaded - could you please answer whether using
/sys/bus/pci/devices/0000\:03\:00.0/resource0
works for you (on systems that have resource0)?

Since I don't consider this a critical fix (there's no reason driver won't go
up, and if it does not, there's a simple workaround by specifying the /proc
interface, that is slower but works), I don't think this should go into OFED 1.1.

Unfortunately, I never got a small bugfix patch against the latest mstflint -
the patch I saw posted touches all kind of things all over the code -
so I can't insert it in trunk, either.
