Enabling Text mode on Graphics

Hello,
 
I am working on the Graphic Card 69030(asiliant driver) porting on MIPS
Board. I need to implement the Text support on Graphics. I am
implementing the Framebuffer concept, where I have taken the reference
of the BEBOX Frame Buffer implementation concept. Will the card supports
the Text mode on Graphics and how to implement in NetBSD? And when I
call wsdisplay_cnattach() from the attach function of FrameBuffer (This
is done after the initialization of the Hardware), the code will hung in
cn_tab of (/dev/wscons/wdisplay.c). At this position the card will get
detected and only able to display some color (which varies every time).
This color I am not able to change also. The Hardware is just getting
initialized, but it is not allowing me to write anything with respect to
color or Text. Please put some light on it. what are the factors do I
need to consider to enable the Text mode on Grahics mode/video mode.
 
Regards
Swamy
