No, you don't need to upgrade the headers. I'm running 126.96.36.199 with no problems. You should just use root=/dev/hda1, since that it is. You sure ext3 and the sata driver aren't compiled as modules?
To stop the message scrolling, just press Scroll Lock...
And it is ok to keep them in the same folder, they won't get mixed up..
Try to see the messages and then report back...
