Keith,

have you looked at gdb/mi/mi-cmd-disas.c (yes the code is nasty) which 
calls the TARGET_PRINT_INSN() with a ui-out builder.

If the main function was split in two would the second half do what 
you're after?  You can check the output by looking at the 
mi-disassemble.exp test (or the doco which might be easier to read :-).
