problem with video modes switching in Xorg 7.3

[obscenum]

Hi all,

After upgrading Xorg to version 7.3 I can no longer switch video modes 
with
ctrl-alt-kp[+-] and X chooses 1024x768 as a default resolution to start,
however it should be 1280x1024 (pls see attached xorg.conf). As a 
temporal
workaround I'm using xrandr to set correct resolution after X server 
starts up.
Output of xrandr and relevant parts of xorg.conf are following. Any 
points regarding
this problem are very appreciated.

# xrandr
