Is the kernel really a 32-bit kernel even for Linux 2.6?

If so, then yes, OpenAFS doesn't support that configuration.  Someone
would need to write a Linux 2.6 configuration for 32-bit SPARC.  It
probably wouldn't be that difficult; most of the work would be merging the
sparc_linux24 files with the sparc64_linux26 files in some appropriate

I wonder if that kernel module actually works.  Of course, without the
userspace afsd, it's sort of hard to tell.
