Ah, that explains it. Thanks, Peter.
That's the same issue I was having trying to get Fedora Core 4 booted (yes, I know, but I wanted to tinker

. It does boot with 2.6.17-rc2-linode19, after a fashion. It starts in single-user mode (not sure why yet, inittab is defaulted to 3), but 'telinit 3' brings it all the way up.
I've also got a problem with 'unable to open an initial console', but that's probably an artifact of the devfs->sysfs transition that I haven't diagnosed yet. So no login on the console, but ssh works just fine.
