I also found a Reddit thread from 2020
(https://www.reddit.com/r/linuxadmin/comments/e6ox9t/on_most_linux_systems_why_is_the_kvm_kernel/)
so it goes back to that far, the OP had Ubuntu 19.10. There's a link to
a kernel commit too in there which explains things a
little. https://git.kernel.org/linus/644e9cbbe3fc032cc92d0936057e166a994dc246

OTOH, there was some web page in nz where someone explained the same
issue: VBox worked in Bookworm but not in Trixie and he had to
blacklist. So, it seems there might be something there. I dunno, all my
Bookworm and Trixie systems load kvm and kvm_amd or kvm_intel by default.

Could it be there was some postinstall script in Bookworm times which
handled blacklisting and unloaded the kernel modules so Virtualbox was
ready to go?
