I have a multiseat configuration based on two pci/e radeonhd cards (primary:RS780, secondary:rv710). Both cards are working fine with radeonhd-1.2.4, but when i try r6xx-r7xx-support radeonhd brunch to get 2D hardware acceleration only primary videocard was initialized. I try to initialize videocards separately, but this does not help also.
The initialization of secondary chip(rv710) finished with the messages
(--) RADEONHD(0): Detected an RV710 on an unidentified card
(II) RADEONHD(0): Mapped IO @ 0xfe7f0000 to 0x7fc084b5c000 (size 0x00010000)

As i can see radeonhd driver try to use ATOM BIOS of primary videochip to boot secondary videochip. As result it did not find videoram and failed.

I hate to say this, but: Me too.
Just after I mailed my problem to the mailing list, I found out it was already reported here.
Does this issue occur with the preferred ati driver (xf86-vide-ati)? If so, please move this to the Driver/Radeon component.
Development of radeonhd has pretty much halted and development focus is on the ati driver. Please see http://www.x.org/wiki/radeonhd
If the issue does not exist in the ati driver (or if there is no response to this message), this bug will be closed as WONTFIX unless someone contributes a patch.
the bug does not exist anymore, thanks!
