I had the same "stacked" double image with MythTV on Fedora 8 using an 
X1200 card. I fixed it with the following xorg.conf device entry:

Section "Device"
         Identifier  "aticonfig-Device[0]-0"
         Driver      "fglrx"
         Option      "VideoOverlay" "off"
         Option      "OpenGLOverlay" "off"
         Option      "TexturedVideo" "on"
         Option      "TexturedVideoSync" "on"
         Option      "Textured2D" "on"
         Option      "BackingStore" "on"
         Option      "UseFastTLS" "1"
         Option      "XAANoOffscreenPixmaps" "on"
         Bus         "PCI:1:5:0"
EndSection

I also had to wrangle with /etc/ati/amdpcsdb, which (on Fedora) is a 
different text configuration file for the fglrx driver. You might want 
to ensure that all the device entries in xorg.conf have the right 
setting in etc/ati/amdpcsdb. This of course assumes that Ubuntu's fglrx 
has the same non-standard configuration as Fedora's.

Can't help with this - I'm not a Ubuntu guy.
