I'm experiencing quite the same bug.
On a Dell Vostro 1500 (NVIDIA GeForce 8600M GT), I have an external monitor with maximum resolution 1280x1024.
The strange thing is that it's not happening every time I plug it in, but it happens randomly.
In this moment, I'm looking at the external monitor, with the 1280x1024 resolution. Yesterday, for example, there was a moment when the resolution was not correctly set, and I found myself with a 1440x900 resolution fit in a 1024x768 (the screen moved as I moved my mouse - hope this is understandable, I'm Italian).
Rebooting "fixed" it (although maybe at next reboot I'll find myself with the wrong resolution).

greping /var/log/Xorg.* searching for "EDID" didn't show any result, but
"get-edid|parse-edid" shows problems (I'm attaching the complete
output):

[some text..]

VBE/DDC service about to be called
        Read EDID

        Performing real mode VBE call
        Interrupt 0x10 ax=0x4f15 bx=0x1 cx=0x0
        Function supported
        Call failed

The EDID data should not be trusted as the VBE call failed
EDID claims 32 more blocks left

parse-edid: EDID checksum failed - data is corrupt. Continuing anyway.
parse-edid: first bytes don't match EDID version 1 header

EDID blocks left is wrong.
Your EDID is probably invalid.
