Default Can't set the resolution of 1366x768

I use Mandriva PWP 2009.0 X86_64, with 173.14.12 version of nvidia drivers. I can't get the resolution 1366x768 which I set in Mandriva Control center. It alway fall back to 1280x720. This is what I get in Xorg.0.log:

(--) NVIDIA(0): Connected display device(s) on GeForce FX 5200 at PCI:1:0:0:
(--) NVIDIA(0): Philips 191EW (CRT-0)
(--) NVIDIA(0): Philips 191EW (CRT-0): 350.0 MHz maximum pixel clock
(II) NVIDIA(0): Assigned Display Device: CRT-0
(WW) NVIDIA(0): No valid modes for "1366x768"; removing.
(WW) NVIDIA(0): No valid modes for "1360x765"; removing.
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0): "1280x720"
(II) NVIDIA(0): Virtual screen size determined to be 1280 x 720
(--) NVIDIA(0): DPI set to (79, 79); computed from "UseEdidDpi" X config

In xorg.conf file I have this settings for resolution:

Section "Monitor"
Identifier "monitor1"
VendorName "Plug'n Play"
ModelName "Philips 191EW"
HorizSync 30-83
VertRefresh 56-76
Option "PreferredMode" "1366x768"

# Monitor preferred modeline (59.8 Hz vsync, 47.7 kHz hsync, ratio 16/9, 84 dpi)
ModeLine "1366x768" 85.5 1366 1436 1579 1792 768 771 774 798 +hsync +vsync

I have dual boot on this machine, and Windows XP have no problem getting this resolution. I read on some forums that nvidia drivers for linux don't support resolutions which can't be divided with 8, is that true?
