I verified this issue is still present with 2.6.35rc6 and the current X
packages on xorg-edgers. Something new I noticed with Ubuntu 10.04: if I set
GRUB_GFXMODE=1400x1050 (the native resolution of the LVDS) in
/etc/defaults/grub, then the console actually uses the correct resolution.
Howerver, once X starts, the new FB switches to 800x600. The Xorg.0.log
indicates that S-Video is falsely detected as being connected, while in fact
nothing is attached. 

What can I do to further isolate the cause of this issue?
