So that leaves us with a puzzle: does that mean that 2.6.38-3~bpo60+1
fixed it (forgetting about the drm.edid_strict parameter for a moment)?

Ah, sorry I wasn't clearer before. The edid_strict patch is something
Alex had been thinking about but it is not in appliable shape (it does
not have strict enough buffer size checks to cope with e.g.
maliciously made hardware). And of course it's even better if it is
possible through a driver change to get an uncorrupted edid.
