Unfortunately this hasn't worked.  The log still just has:

[   678.002] (EE)
[   678.002] (EE) Backtrace:
[   678.002] (EE)

Maybe X backtraces aren't implemented on ARM?  Or I need to install some 
more -dbg packages?

Display with this driver appears to work, but X still segfaults when I 
touch a button in my UI.  It needs a piece of Xorg conf like this:

Section "Device"
     Identifier     "Video Device"
     Driver         "omap"
     Option         "Debug"         "false"
     Option         "HWCursor"      "false"
EndSection

More news as I have it....
