Surely you can fix that. :^)

Could you describe the display?  Do you have a rolling screen, flickering, 
amorphous areas of wrong colors, or anything of the sort?  Or are all the 
problems at the pixel level?

What kind of monitor are you using, anyway?  Does your card output to a VGA 
port, S-Video, composite, DVI, proprietary connection, what?

Can you temporarily swap the RAM?  If that fixes it, then that fixes it.  If 
not, look elsewhere for the problem.

Try 4.3.0, perhaps?

May we see this file?

Does your kernel have support for this?  If so, mknod the file in question.  
Read linux/Documentation/devices.txt for more information.

Does this card work with svgalib or fbcon?

Are you having palette problems, that is, wrong colors?

Again, what kind of monitor?

Which one do you use?

Could this be the problem?

Does your computer have MTRR support?  If so, enable it in your kernel.

Here's your showstopper.  You don't have a /dev/mouse.  If it's under a 
different name, adjust your XF86Config file.
