Sorry to reply to myself in response to comment #67 (my last post):

In git-commit 2b0cdd9448a24ea067b0d78f319b99c1041df2e0 of module
xf86-video-ati a change was committed which enabled the retrieving
the tmds-pll-config-values from the BIOS. The same commit also changed
the default tmds-pll-init-values.

When disabling the BIOS-sequence, our blanking problem disappeared
(mostly) and we got the former (better) behaviour back. So it seems,
getting the info from the BIOS is not fully reliable (at least for our
cards). I left the changed default tmds-pll-init-values as defined in
the commit mentioned above.

I am more than willing to help in debugging this problem (we have
a rather big "testbed") but need some hints what the tmds-init-values
mean and how the BIOS sequence is expected to work.

Thanks to the author of comment #44 which gave the important hint.
