Only whats on the website.  Your best bet is to ask.
The current releases work for kernels up to 2.6.18 without
any major issues.  I should be doing a release this week with
everything up to 2.6.22 supported fully.  Just finishing off the
testing.

I have used the safenet driver on SuperH and ARM platforms. It works
fine there.  I don't have any way to test it on x86 though.

It should work fine on 2.6.17, load everything with debug enabled
and see what happens.

If you are running on an x86_64 system, disable all the code in
"random.c" however,  it was broken on 64bits arches in older versions.

Cheers,
