Multicard and multiseat for radeon doesn't need vgaarb; use KMS instead and
your cards will both come up at boot.

humm, seems not issue with vga arbitration. I'd guess maybe missed mode
setting. Try to start an app on the monitor black and see if connects. If
succeeds then the arbiter is doing its job okay.
