2.6.8 is an old kernel, you could very well be hitting a kernel bug

I will try that soon.

Also,
you're not including sources to your module so it's impossible to tell
whether you're doing something wrong.

Below is my baby module which only uses kmalloc and kfree for my device
structure. I found the slab corruption address is the address of the structure.
It seems to be a bug for kmalloc and kfree.

I haven't looked at your source code yet, but in addition to testing with a
recent kernel version, it may help to enable lots of kernel debug options.
Could you try that too, or do you already do that?
