If you have access to source codes you may look at gtkcellrenderertext.c 
file for function: gtk_cell_renderer_text_render().
There you should see that "state = GTK_STATE_INSENSITIVE" is what you 
are looking for.
I guess, the simplest way is to code your CellRenderer derived from 
GtkCellRendererText, and reimplement function render, so, it should look 
at some CellRenderer::property and decide what state should be set for 
current cell.
Actually, you only need to reset "render" function for 
GtkCellRedndererClass this way:

static void my_gtk_cell_renderer_text_render(...)
{
...
}

some_function()
{
...
GtkCellRenderer *text_render = gtk_cell_renderer_text_new();
GtkCellRendererClass *render_class = GTK_CELL_RENDERER_GET_CLASS( 
text_render );
render_class->render = my_gtk_cell_renderer_text_render;
...
}
