It didn't help.  The original oops says the problem was in strcmp.  It
was a GPF, which suggests to me that one of the arguments is NULL. 
Since ops->name is checked at the beginning of the function, the only
other possibility is that alg->ops->name is NULL.  I added a bit of code
to check for this, and it turns out that one of the strings was indeed
NULL.  I didn't know where to go from there in debugging, but I hope it
helps.

Thanks,

Thomas Tuttle
