Well i maybe out on thin ice here but....you seem to load some modules that i don't think is necessary.
DBE, try to remove thar one, check in the 'Module' section in your XF86Config file and try to remove one and try.
I got these loaded:
type1 <- fonts
freetype <- fonts
glx <- gl
extmod <- gl extensions
afaik these are the only ones you need =)
More than that i cannot help you....i can't see any faults in the logs so.
Oh yes, if you want to try older versions of the NVIDIA drivers try this adress, if it's not that one they have an archive, i've been there:
