Thanks Gary, I'd not come across that before. I tried it (and lots of other 
fiddling with xorg.conf) over the weekend and unfortunately it doesn't 
seem to work. Here's my current /etc/X11/xorg.conf file:

    Section "Monitor"
        Identifier    "HDMI-0"
        VendorName    "LG"
        ModelName    "42LM620T"
        Option        "UseHotplugEvents"    "false"
        Option        "Primary"        "true"
        Option        "DPMS"        "false"
    EndSection

    Section "Screen"
        Identifier "Screen0"
        Monitor    "HDMI-0"
    EndSection


which appears to be detected:

    ~$ grep "xorg.conf" /var/log/Xorg.0.log
    [  1114.119] (==) Using config file: "/etc/X11/xorg.conf"

but isn't having the desired effect.

I suspect that the "UseHotplugEvents" option is NVidia specific, as I can't find any mention of it in the 
manpages for  xorg.conf  or  radeon . It looks like EDID options (like 
"UseEDID") are nvidia specific too, so xorg.conf with ATI is looking 
like a dead-end :(

I'll
 keep searching and trying things (including your EDID kernel 
suggestion), but in the end I may have no option but to revert back to a
 legacy kernel and proprietary ATI driver that
 supports my Radeon HD 4250. In the meantime any other solutions would be most welcome. Thanks,
