Thanks for the answer. In fact I tried the MonitorLayout option and
the randr-1.2 branch before reporting the bug and this does not work.
The solution was/is a patch which showed up in bug #2859, comment #73
(not reading the TMDS-PLL values from the BIOS but using the default values
from the driver). I had this change in the driver which worked before
but thought this is unrelated - sorry about this.
With this change the DVI-output an our T51 works.
This shows the real problem: Our TPs R51 seem to be one more system which
contains invalid BIOS TMDS/PLL entries which the driver should ignore.
In comment #79 of bug #2859 it is proposed to detect invalid values
in these tables and ignore them. But hot to recognize that the entries
are invalid??
