Carlos might have a better list somewhere, but off the top of my head:

- binutils needs a lot of work for 64-bit palinux. It barely works for 
  building 64-bit kernels
- gcc's hppa64-linux target should be in decent shape in general, 
  although right now it cannot bootstrap itself (for 3.2 at least,
  not sure about 3.3... I have one patch from Dave to test)
- kernel assumes userspace is 32-bit in several places (e.g. syscalls,
  signals, ..) these need to be cleaned up
- there is no glibc support for hppa64-linux, this needs to be written
- there is no gdb support for hppa64-linux, this needs to be written

i'm sure there are more, but you get the idea -- in general nothing is
done yet and this will need a LOT of work; meanwhile we still have lots
to do for kernel and 32-bit userspace. If you have the time, and want to
hack on userspace stuff I can give you a list of interesting projects :)
