Have not followed all this thread but have FC4 on VIAO VGN-T150
successfully using 1280x800 res.  855resolution patch works for me on
855 chip.  Put following in /etc/rclocal.d for automagic mode setting at
boot.
	#set vbios to 1280x768 mode
	855resolution 5c 1280 768

One oddity....had to go to Desktop > Preferences > Screen Resolution and
choose 1280x768 the first time.  Now boots to that mode every time.
Don't recall if I did anything special with xorg.conf or not.  Laptop is
not presently available but will post that file tonight if you think it
would be helpful.
