The card has 128 Mb of ram, and my system has 3 Mb of RAM. Is there any reason the ioremap() call works on 2.6, but doesn't on 2.4? I've tried searching google for hints, but nothing has turned up. Is there any way to test 2.4 with my radeonfb and all of my memory? Thanks, Jurriaan -- proof by exhaustion: An issue or two of a journal devoted to your proof is useful.
