Unless called with -o, d.rast erases the screen, which removes the
font setting (the monitor remembers the actual font setting, but the
information is removed from the "pads", which is what d.save uses):

[display/d.rast/display.c lines 38-40]

    /* cell maps wipe out a picture, so we clear info on the window too */
    if (!overlay)
	D_clear_window();

Try running d.font *after* d.rast.
