Other than that I've never seen an XFree86_DDC_EDID2_RAWDATA property,
so would be interested to see your log file.
Unfortunately, I have been unable to reproduce this result. I swapped
out My Mistubishi Diamond Pro 2060u for a Lacie electron 19b IV for some
other testing. When I put the 2060u back on to attempt to reproduce this
DDC_EDID2 anomoly, it did not reproduce it. The log file is attached
below, in case you might be able to extract any pertinent information on
this, even if I could not reproduce the results.
However, I'm still left with the dilemma of being unable to inventory
all the monitors on the system. I realize that the network transarency
schema says that in some instances this does not make sense to do.
However, in Windows, Mac OS9, and OS X there is a mechanism to retrieve
information on the monitors on the desktop (like each one's EDID), be it
virtual or not. Is there no equivalent in X?

I have more machines than monitors, so haven't looked very hard at the
dual head case, and wouldn't be suprised if there are cases where
the second head EDID data is wrong or not made available.
