we use omapdrm not omapfb so none of those options will have any
effect. its all auto detected and auto setup. if the edid data is not
read from the monitor you will get 1024x768 only. ive not tried the 3.5
based kernels as im not at home where i have access to a monitor. 

you shouldn't use  the xpfa repo there is no need Fedora 17 will update
and work just fine with whats in Fedora 17. you could try switching
which port you plug the monitor into. you would also need to look at
the output of dmesg to see what is happening.
