I am using a single-monitor 1280x1024 setup with a 256M FireGL V3700, and a similar issue is exhibited (differing only in log output). I have successfully used a dual-monitor setup with this card where _both_ monitors had higher resolution than this one; I agree that this is not likely to be caused by a lack of sufficient memory to start an X server.
The issue remains when no compositing manager is running, and on a system that has been booted recently.
