Have you tried comparing the contents of the various initrds?

$ gunzip -c /boot/initrd-2.6.10-1.760_FC3.img | cpio -t
etc.

When you say you downloaded and compiled the 2.6.10 source, do you mean
the kernel.org (vanilla) source, or did you take a Fedora kernel SRPM
and add your DVD driver patches to that? The latter approach would
probably achieve better compatibility as it would include whatever
patches the regular Fedora kernels have.
