I have compiled quite a few kernels exactly after my cheatsheet
(from at least 2.4.21-rc1 up to my currently running 2.4.21-lvm)
and it works. At times I may have to hand-patch because of
trivial changes to get the VFS-lock patch in, but ... that's it.

It MIGHT be that LVM 1.0.7 is in sync (or at least not damaging)
to the VFS-lock patch for 2.4.20. I *have* had problems in the
past (I tried VFS-lock and the LVM and it failed), but I cannot
vouch that they are there for kernel 2.4.20/LVM 1.0.7.
