#3) Anytime I try to dump the instruction at the current IP such as:

I get this - which means it's not actually reading or displaying the memory properly, since those look to be what you would see if it was all 0 in memory (or maybe it's all 0xff - whichever).l

qemu doesn't report memory errors to GDB.  It reports -1 values
instead.  This is annoying.  I think I posted a patch for it once and
never followed up when it was ignored.

This is not correct: an error is correctly reported by the QEMU gdb stub...
