We have a similar problem: A HD6570(TURKS) card with RS780E chipset. When
booting, DVI output is good, but VGA output is black screen; after X
started, DVI is still good and VGA blinks forever. We have tried
3.4~3.9-rc7 kernel, all kernels after the commit "drm/radeon: properly
handle mc_stop/mc_resume on evergreen+" has the same issue.
