No I am not aware of any patch fixing this issue.

The problem (as the thread says) is that ps_lgetregs is not implemented 
inside the gdbserver on PPC (or any other machine that uses 
PEEKUSER/POKEUSER to access its register sets).

You should be able to jury rig a version by copying the code in 
ppc-linux-nat.c:fill_gregset() into the ps_lgetregs function and 
modifying the code to target the gdbserver register cache rather then 
the gdb register cache.

There is, of course, a proper to way to do the above but you might want 
to confirm the above works first ;-)
