Along the same lines, but more automated:

% ./dump-insn-ppc.zsh 7c0048ce
   0:   7c 00 48 ce     lvx     v0,r0,r9
% cat dump-insn-ppc.zsh
#!/bin/zsh
objdump -b binary -m powerpc -EB -D \
  =(perl -e 'print pack "N", hex $ARGV[0]' $1) | tail +7

The version of objdump I'm using doesn't like to read from a pipe for
some reason, but =(...) is a handy zsh feature that automatically
creates and removes a temporary file. The "-EB" (big endian) is needed
because I'm actually running this on an x86 (using the Debian
"binutils-multiarch" package, a version compiled with support for a
whole bunch of architectures besides your native one).
