   There is a rivafb that supposedly works with the "nv" driver.
I've never tried it.

   You can't.  When the server X server enters the VT it is going
to reinitialize the mode.  When it leaves, it is going to restore
the mode it initially saved.  Those are the rules.  The particular
instance of the server doesn't know that another server is just 
going to reset it to the same mode.
