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.
