ddcprobe is not part of X. As a side note, the Dell 2000FPW DFP has a hardware flaw which provides incorrect EDID data. As such, even if DDC probing were to succeed, it will end up with incorrect configuration. For correct operation, this panel must be manually configured.
Unfortunately, some videocard/monitor combos can't be probed with the real-mode based monitor probing that we do as they don't support it :( Doing more requires X to export things which it currently doesn't (but the longer term plan is to make it less necessary for it to even do so)
