[the /arch/setup menu autoadvances when you leave Configure System and if you click Done and downarrow anticipating moving to the next item,  you can easily miss configuring the bootloader (I did ;-)]

I don't understand how to control the new KMS stuff. I have check the kde4 settings for Display Size and Orientations, but the maximum allowed is 1152x864:

Listmates, I have more info. It looks like an xdpy problem:

resolutions should be 99x99. How do I fix this ??
