[Sony Vaio TZ] Xorg mapping wrong resolution

Question

I recently bought a Sony Vaio TZ - awesome piece of equipment - but noticed my actual Xorg resolution was higher than what the specs said (by 2 pixels). This is kinda annoying...
Xrandr output before I use xrandr to set the correct resolution:
[root@hermes stijn]# xrandr
Screen 0: minimum 1024 x 768, current 1368 x 768, maximum 1368 x 768
default connected 1368x768+0+0 (normal left inverted right) 0mm x 0mm
1366x768 60.0
1360x768 60.0
1024x768 60.0
1368x768 60.0*
As you can see it says it detects 1368x768 as maximum resolution but lists the correct resolution (1366x768) as a possibility too.  My first reaction was to generate a modeline that would make Xorg behave, but that does not have the desired effect (it returns a 1368x768 line!):
[root@hermes stijn]# gtf 1366 768 60
# 1368x766 @ 60.00 Hz (GTF) hsync: 47.58 kHz; pclk: 85.64 MHz
Modeline "1368x766_60.00" 85.64 1368 1440 1584 1800 766 767 770 793 -HSync +Vsync
I have tried setting a Modes line in xorg.conf like this:
Modes "1366x768"
but that gives me the following message in Xorg's log:
(II) I810(0): Not using mode "1366x768" (no mode of this name)
Adding a 'Virtual' line with the correct dimensions like this:
Virtual 1366 768
doesn't do the trick either.
Grepping Xorg's log for both X sizes returns the following:
[root@hermes stijn]# egrep "1366|1368" /var/log/Xorg.0.log
(II) I810(0): Display Info: LFP (local flat panel): attached: TRUE, present: TRUE, size: (1366,768)
(II) I810(0): Size of device LFP (local flat panel) is 1366 x 768
(II) I810(0): Lowest common panel size for pipe B is 1366 x 768
(II) I810(0): PanelID returned panel resolution : 1366x768
Mode: 60 (1366x768)
XResolution: 1366
Mode: 61 (1366x768)
XResolution: 1366
*Mode: 62 (1366x768)
XResolution: 1366
(II) I810(0): Not using mode "1366x768" (no mode of this name)
(II) I810(0): Correcting stride (1368 -> 5504)
(**) I810(0): Virtual size is 1368x768 (pitch 2048)
(II) I810(0): [drm] init sarea width,height = 1368 x 768 (pitch 2048)
Why the heck does the i810 map to this resolution? Xorg recognises the 1366x766 correctly no? Is there a way to make Xorg use 1366x766 without having to resort to xrandr? For what it's worth, I had this issue also with the vesa driver.

Ok. I went with xmodmap because xbindkeys basically does the same, only requiring you to install an extra package .
I mapped the eject button to eject too (surprisingly, as I didn't know at first the slim drive had a button, I thought the whole thing was pressure sensitive...). I mapped the AV button to a fullscreen instance of VLC .
I fixed all Fn keys except for the zoom key (don't know how to map that to e.g. Opera's zoom functionality yet) and the external VGA connector which I should still write a script for.
Anyways, here's my handler.sh patch:

Xmodmap gives names to the Fn volume keys and the multimedia keys, and they are bound to the related actions through my Openbox rc.xml.
