Thank you for your guidance. Below my observations:
1. Set to hidden, radio blocked or something like that in the BIOS setup

Conducted a bunch of experiments, still unable to get the driver to
work.
- Tried Option 'PanelSize 800x480. Driver seems to create the right

- May mean that I am hitting a different bug.
Attached lspci,
Public bug reported:
Using jaunty on OQO 01. LCD is 800X480 (common for Palmtops and some Netops).
Driver goes to 800X600 and screen is black.
xorg.conf Modeline to manually provide proper panel size is ignored by
the driver.
** Affects: xserver-xorg-video-siliconmotion (Ubuntu)
