It turns out I was wrong on both counts. The oldest supported version
is 2.6.25, not 2.6.24, and yes that is hundreds of versions. :)
I got curious and counted: we currently have single-source support for
541 official Linux kernel versions. That's not counting current "rc"
versions (which are now supported), or RedHat's backport abominiations
(which occasionally require special support).
Within those 541 versions there are only about five or six distinct
incompatible API subsets to worry about, so it's not as impressive as
it sounds.
