@Arne: I can't get that to work. The screen captures on your website are from a virtual machine (qemu?), so they need not be correct because hardware is not accessed directly. And indeed, you write "0xFFB00000,0x100000" in one place and "0xFFB00000-0x100000" in another. Could you paste the exact kernel line that you use on the actual menu.lst on the laptop? I'm very interested in this option...
