Here's the situation. I just installed Debian 3.0 testing and I set it up so that I was using their lvm10 package (version 1.0.4-6) for /usr, /var /home, etc. (NOT /) It works fine off the kernel that Debian uses in its install (2.4.18-bf2.4). BUT, if I install a stock Debian kernel with apt-get (kernel-image-2.4.18-k7), lvm cannot see my physical volumes at boot-time.
Make sure that the stock kernel has LVM installed, then upgrade to 1.0.6 (via http://www.sistina.com/). Building a 2.4.10 kernel w/ 1.0.6 (if you want to stick with 1.0) should give you the best results.
