Text mode should work as far as i know. Getting graphics working
should not be too hard. eCos uses the Microwin code for its
graphics. Im sure there must be a basic VGA driver around somewhere
you can port to eCos.

You have quite high requirements. eCos was designed to be used in
deeply embedded system, and your requirements don't fit what i would
normally consider a deeply embedded system.

So lets take a step back and look at the system as a whole. What are
you trying to build? What are the requirements in terms of real time?
Do you need an RTOS or will an plain OS do? If you don't need an RTOS,
Linux seems like a much more sensible way to go.
