Driver 190.40 GeForce GT 240M xorg-1.6.1 hangs on X session exit

[swizard]

Problem with recent 190.40 driver on Acer Aspire 5739G laptop.

The first problem was with invalid EDID response:

(--) Nov 10 17:37:02 NVIDIA(0): --- EDID for AUO (DFP-0) ---
snip
(--) Nov 10 17:37:02 NVIDIA(0): Detailed Timings:
(--) Nov 10 17:37:02 NVIDIA(0):   1366 x 768  @ 60 Hz
(--) Nov 10 17:37:02 NVIDIA(0):     Pixel Clock      : 69.50 MHz
(--) Nov 10 17:37:02 NVIDIA(0):     HRes, HSyncStart : 1366, 1414
(--) Nov 10 17:37:02 NVIDIA(0):     HSyncEnd, HTotal : 1446, 1437
(--) Nov 10 17:37:02 NVIDIA(0):     VRes, VSyncStart : 768, 771
(--) Nov 10 17:37:02 NVIDIA(0):     VSyncEnd, VTotal : 775, 806
(--) Nov 10 17:37:02 NVIDIA(0):     H/V Polarity     : -/-

For which the driver complains:

WW) Nov 10 17:37:02 NVIDIA(0):     Mode is rejected: This mode's horizontal sync end (1446)
(WW) Nov 10 17:37:02 NVIDIA(0):     exceeds the horizontal total size (1437).

After some googling I managed to force it works with following xorg config:

Section "Monitor"
   Identifier  "DFP-0"
   VendorName  "AUO"
   ModelName   "AUO"
   DisplaySize     340 190
   HorizSync       48.4 - 48.4
   VertRefresh     60.0 - 60.0
   Option      "DPMS"
   Modeline "1366x768_60.00" 69.5  1366 1414 1446 1447  768 771 775 806  -HSync +Vsync
EndSection

Section "Device"
    Identifier "GT 240M"
    VendorName "nvidia"
    Driver  "nvidia"
    BusID   "PCI:1:0:0"
    Option  "ModeValidation" "NoDFPNativeResolutionCheck"
    Option  "ExactModeTimingsDVI" "true"
EndSection

Section "Screen"
   Identifier "Screen0"
   Device     "GT 240M"
   Monitor    "DFP-0"
   DefaultDepth   24
   SubSection "Display"
      Depth     24
      Modes   "1366x768_60"
   EndSubSection
EndSection

The second problem is that after quitting xorg the black screen appears and whole system hangs. I don't know how to fix or debug it, maybe the driver bug?
