Yes and no. :-)

The debian architecture is sparc which means 32 bit useland. The
hardware is 64 bit since the Linux kernel no more supports 32 bit
sparc hardware for quite a while. Hence all kernels (since IIRC Lenny)
are for sparc64 hardware. sparc64 as Debian architecture has both,
64-bit kernels and userland.

Think of "sparc" like running Debian's i386 architecture with
linux-image-amd64 kernel which is available as both, i386 and amd64
packages. Sparc is similar, only that all "i386" ("sparc") kernel
packages contain "amd64" ("sparc64") kernels.

It's a machine which runs with sparc and has a sparc64 (now again the
Debian architecture) chroot.
