	Hmm, and Hmmmmm. It just occured to me that I have no video mga 
	in mykernel GENERIC.  I can't find mga.ko (or any other kernel
	object file *anywhere*.  

	Rebuilding my kernel is not a big deal.. Can you or anybody else
	clue me in on this?  How do I revert back to the earlier mga
	driver?  In other words: where is the  1.4.7 src.

	A last tidbit is that while things DO load, the screen is almost
	dark.  --My  CRT is in great shape.

	thanks muchly,
