Hmm.  Try eyeball-hunting for lines that have a 65.15 dotclock.  (Well,
that's what my LCD has anyway.)  On a 1024x768 class LCD panel under the
"SVGA" type server, I asked vidtune for the lines which were in active use
on the system I was on at the time.  8x6, 6x480, 10x7... widely varying
horiz and vert, all the same dotclock.

Best I can think of without having a Vaio to play with.

If you capture the output from the good 3.3.6 session opening up, it may
include notes from the server about discoveries it has made about the video 
panel.  Possibly even a model number.

a bunch of keywords ("LCD panel nnnnn clock" where nnnnn is the panel
model number, to google! would be my first shot) and see if there are
(I won't say technical, marketdroids abuse that, but) repair technician's
specs on it somewhere.  If they're available in open space and legal, the
X4 gang can use them to improve its LCD handling.

Best of luck
