Also, I kind of was hoping that once I could use 1280x720 for both the
console and the X screen, it would would allow me to switch between the

extra syncing time. Is this expected behaviour?
You mean switching underscan off and on or a VT switch? The hw has to
reprogram the mode when it changes the underscan. As for a VT switch,
it should just be changing the crtc base, but IIRC there was a bug
where X and the console used slightly different modes in some cases.
VT switch. I use video=1280x720@50 on the command line and select the
corresponding EDID resolution within X. Is this bug still pending or is my
scenario supposed to work?
You may be seeing this issue:

"In the absence of the user specifying an overriding monitor
configuration, trust the KMS drivers to have correctly probed the output
modes."
Well, in my case I *am* specifying an overriding monitor configuration.
Is there still a chance that video=1280x720@50 could be meaning s.th.
different then the corresponding mode in X that I explicitly choose.
