Let's thin about this logically. A kernel does not get told it's
version, it already knows that, and modules are versioned too. A kernel
finds it's modules by looking in /path/to/modules/`uname -r`

So, either the version string is wrong in the kernel (possible I suppose
if you copy and old .config and male oldconfig goes wrong somehow) or
you have the wrong modules in the wrongly named directory.

If the version string correct if you runs trings against any of those
not-loading modules and grep for "vermagic"?

Does the correct kernel version show up when looking in strings of the
image in /boot?

[working theory: the kernel throws permission denied errors when it's
asked in weird ways to load wrong versioned modules. Pure speculation,
I've never done this at all and don't know what the error is]
