This looks wrong and very likely the root cause of your issue. Try to
force it to the proper value set in the bios. the unit is kB.
Option "VideoRAM" "65536"

There is a bug already filled for this :

Also, either the monitor doesn't send an EDID or it's not read properly.
You might need to force HorizSync and VertRefresh to some sane values
(check your monitor manual).

It would be interesting to compare the F12 Xorg log with the F10 xorg
log. I'm wondering if this is a regression.
