I was able to get dual-head and Xinerama working under 7.10 Gutsy using the X11 config file additions from LaptopTestingTeam/ThinkpadR52/Multihead which are reproduced below: 

## The following are for Multihead/Fancy setup.
################################################

# Select between these layouts by using  X -layout "IDENTIFIER"
# "Single" is a proof-of-concept that only two 'screen' lines should be needed

# The first Pointer and First Keyboard are implicit so
# do not need to be specified, only the /extra/ Synaptics.

Section "ServerLayout"
        Identifier      "Single"
        # Does not work with 'Default Screen1'
        Screen          "Default Screen0"
        InputDevice     "Synaptics Touchpad"
EndSection

Section "ServerLayout"
        Identifier      "Dualhead"
        Screen          0 "Default Screen0"
        Screen          1 "Default Screen1"
        InputDevice     "Synaptics Touchpad"
EndSection

        Screen          1 "Default Screen1" LeftOf "Default Screen0"

        Option          "Xinerama"                      "on"

# Additional Driver entries for the card.  The only differences
# are the 'Screen n' line and 'Option MonitorLayout'

# I wonder if the 'Screen 0/1' option should really

        Screen          0

        # NOTE: trying "LFP,CRT" crashes the machine solid!
        # This cannot be moved to the "Screen"/"Layout" sections...
        # Seems to have to be the same Driver as "Screen 0"
        Option          "MonitorLayout"         "CRT,LFP"
EndSection

Section "Device"
        Identifier      "Intel Corporation Intel Default Card1"
        Driver          "i810"
        BusID           "PCI:0:2:0"
        Screen          1
EndSection

For testing, I mainly used a setup such as: 

/usr/bin/X -layout "Multihead" ; less -S /var/log/Xorg.0.log

or 

startx -- -layout "Xinerama" &

Conclusion: The resolution issue might be fixable by sticking modelines in and using Options such as NoDDC. Enough things are broken that for high-performance use, the result sucks badly. There it will shine though is using presentations and being able to have notes/demos on one screen and slides on the external CRT. If you really lucky, it maybe possible to flick around betwen slides and demos, allowing you to queue up the other one whilst you're waiting. (It should only be a couple of bits to set the routeing of the display pipes...)

To get GDM to run, I did the rather hackish:

 # To use this server type you should add -query host or -indirect host

which then selects the 'layout' called 'Xinerama' when X is started.
