Same here with my Acer 3810T, Intel GM45, the kernel was built from git pulled today.

v2.6.36-rc2-203-g502adf5

TV1 connected (normal left inverted right x axis y axis)
   848x480        30.0 +
   640x480        30.0 +
   1024x768       30.0  
   800x600        30.0  

and the fb only occupies 1/3rd of the screen, the fbset output

mode "848x480"
    geometry 848 480 1366 768 32
    timings 0 0 0 0 0 0 0
    rgba 8/16,8/8,8/0,0/0
endmode
