A bit more background info:

RS690M is the integrated chipset.
FireMV 2200 (aka RV280) is the PCI add-on card.

Since I am aiming for triple-head, eventually I need both devices.

If I configure the BIOS so that the external graphics (rv280) is
primary, the RS690M completely disappears - even from lspci.

If I configure the integrated chipset (rs690m) to be primary, both cards
are visible and usable, so this is what I do.

Since the integrated RS690M already works properly (both with normal
monitors, and with the flaky one with CustomEDID), I am now testing the
external rv280 card. To do this, I have specified the PCI ID in the X
config (BusID "PCI:3:6:0"), so I am using this card.

The X log confirms this:

"(--) RADEON(0): Chipset: "ATI FireMV 2200 (PCI)" (ChipID = 0x5965)"

Also, when things works (ie. not doing CustomEDID testing), the monitors
connected to the sockets of the external card are activated properly.

So, I think I am running on the right Radeon.

(Please do correct me if I am wrong.)
