Many Thanks(tm), that helped a whole bunch as you can see above.  I 
didn't put the BusID in as its had no trouble finding it at 02:00:0

This is a different card from mine however:
02:00.0 VGA compatible controller: ATI Technologies Inc RV280 [Radeon 
9200 SE] (rev 01) (prog-if 00 [VGA])
        Subsystem: VISIONTEK: Unknown device 7c13
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        Flags: bus master, 66Mhz, medium devsel, latency 32, IRQ 5
        Memory at c8000000 (32-bit, prefetchable)
        I/O ports at a000 [size=256]
        Memory at da000000 (32-bit, non-prefetchable) [size=64K]
        Capabilities: [58] AGP version 3.0
        Capabilities: [50] Power Management version 2

02:00.1 Display controller: ATI Technologies Inc RV280 [Radeon 9200 
SE] (Secondary) (rev 01)
        Subsystem: VISIONTEK: Unknown device 7c12
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
        Flags: 66Mhz, medium devsel
        Memory at d0000000 (32-bit, prefetchable) [disabled]
        Memory at da010000 (32-bit, non-prefetchable) [disabled]

I wish there were some way to punish card makers who plaster the ATI 
logo all over the flippin box when its NOT an ATI reference design 
and 100% ATI chipset in the box.  Fscking jerks.

However, venting about cheap cardmakers aside, this is a major 
improvement, many thanks again Greg.
