I've just uploaded my i815-x11.tgz archive which I use to bootstrap
machines around here. I've been running with it since November, and
it works fine.

(Ignore lkm/agpgart, it got in the archive sometime ago, I just never
took it out).
The archive is at:

I prefer to install lkms into /lkm, so that, as long as I have a root
filesystem, I can load the lkm if I want. Handy, sometimes, and old

These two are in the archive I uploaded.
They've worked fine for me since November last year. I have it on 4 Compaq
