That's the same here with my patch applied. After a suspend -> resume,
the internal panel stays black, the patch doesn't help for that.
Somethig i didn't notice btw., apparently i never suspend->resumed it.

That's different for me:
The internal panel always works during boot, until the radeon kms driver
loads and modesetting gets initialized, then the panel goes dark.
With my patch, the panel then lights up properly immediately, and
external output to dvi/hdmi works as well if i connect anything.
External Displayport panel doesn't work though - stays dark, although it
is reported connected+active in xrandr.
However this is something i got when connecting the external Displayport
panel:

So link training failed, because drm_dp_dpcd_read_link_status() already
failed to read from the dp aux channel.
Without my patch the internal panel stays dark, but plugging in an
external hdmi/dvi display gets both internal+external to light up.
Another way i was able to force the internal panel to stay on without my
patch and without an external display connected is to use the kernel
cmdline option "video=DP-1:2560x1440D" to force the external output on,
although nothing is connected.
The patch is just the result of trial and error, following hunches,
based on reading through the radeon modesetting code. Unfortunately no
real insight into why stuff goes wrong. I also remember disassembling
bits of the dumped atombios a year ago and not finding anything that
looked suspicious to me, but then i'm not experienced at that.

So the same machine model behaves differently with the same patch, and
worse in your case than without it? Maybe different hardware or firmware?
Apples website lists two models of late 2009 iMac10,1 and Radeon HD
4670, to which the patch should apply. One 21.5 inch model without TDM
and a 27 inch model with TDM. Mine is the 27 inch one. I assume yours as
well due to TDM? Attached is the output of dmidecode on mine, not sure
what to look for for differences?
Also attached a dmesg snippet for comparison wrt. SMBIOS version etc.

Lukas idea that some hardware mux gets switched into the wrong position
on models with TDM sounds pretty appealing to me, but how to test?
