But unless you have good reason, you should not wish those old times back. This geometry stuff has caused such a large amount of pain. Set your geometry to the constant */255/63 - depending on precisely what you did, that may already have been what you got from 2.4 anyway. Complain if you have troubles - specify BIOS type, geometry, operating system that has problems booting. I hope we'll find out that everything can be made to work without kernel support.
