implementing vga16fb

Dear Friends,

I am a new to framebuffer, we are implementing kernel framebuffer 
support for the new CPU architecture. I have some basic questions 
related to vga16fb. Please provide some inputs and drive us for 
successful implementation of framebuffer.

Even though we are having PCI ATI Rage XL graphic card, we are 
interested in implementing generic vga16fb for an initial test.

Here are my few queries,

I read that VESAfb is only for Intel(x86) platforms, has any body 
implemented Vesafb on other platforms?

Is vga16fb a CPU architecture dependent? Even though I didn't find any 
architecture dependent sections in the code, Is there any code section 
that to be modified in vga16fb.c?

What are the corresponding files need to be modified for implementing 
framebuffer support for newer platforms.

And lastly, we are testing this framebuffer on 2.6Mhz FPGA(0.16 
Bogomips) with kernel 2.4.7. Are there any other methods (solutions) for 
debugging framebuffer code with out using printk's?

I request your help.

Regards,

Suresh Chandra Mannava.
