I did use a uname hack, so the last kernel tried was compiled for i486
with all chipset bugfix code.

OK, IDE messages: (transcribed)

It doesn't find the time source or the PS/2 mouse very easily, so if IDE
relies on that, that could be the issue. The ide messages all come in a
bundle. Ide1 has no devices.
Booting the same kernel on a newer box gives me these differences.
In place of the first two lines beginning 'PIIX4' I get similar lines
beginning 'VP_IDE'
Then comes
VP_IDE: VIA vt8235 (rev 00) IDE UDMA133 controller on pci0000:00:11.1

I suspect a 1024 cylinder limit problem. The kernel lies above cylinder
4000 and I have no way of finding out where. But grub finds it, loads
it, and boots it! The only other access is under tomsrtbt, which won't
chroot into the new system. Windows 2000 also boots from a grub boot
floppy, but I have to kill that (and my usb connection with it) to come
in under 1024 cylinders. Bios are the latest revision afaict.
Please cc me on this as I am not a programmer and am not on the list.
