Well, you can forget the patch - ti's not needed. I don't know what I was doing wrong, but a rebuild from scratch today (same versions of everything) and it works correctly WITHOUT the patch. Wednesday, when I did this (again from scratch)I needed the patch. I must be losing my mind, however you can add the intelfb with a 865g chipset to your list of known working. It didn't make much sense to me from the start, so I'll write it off to user error/stupidity on my part. B.
