I think you are stuck. I would transplant most of the code into
a user level process and have the interrupt and device driver
just deal with getting the data to and from the user process.
You can theoretically increase UPAGES in /usr/src/sys/i386/include/param.h
but I dunno if that would work, and it would increase the size of
every kernel stack for every process in the system. I get the
feeling that your code eats more then just a few kilobytes of stack.
It doesn't sound like something that belongs in the kernel. The
only other choice would be to rewrite the code into a form suitable
for the kernel's smaller stack.
