I am confused. My second post showed than when things works, X is using
0000:1:0:0, so my preferred card should be PCI:1:0:0, still in the
"things doesn't work case", the "ls /dev/dri/card*" is empty (as shown
in my first post), so would xorg stop complain about missing device node
simply because I specified BusID?

Or, does the fact Xorg fail to start on PCI:1:0:0 /while/ dmesg complain
about something wrong on 0000:02:00:00 confuse you to think I intended
to use PCI:2:0:0? The same fact confused me too, as I expect to see
error message of 00000:01:00:00 in both dmesg and Xorg.log.
