Hmmmm okay...

Alright I can change those for the next version of the patch. Does that 
mean the use of hex output is now a display option rather than a 
separate property type?

Okay, I understand this. I'm highly tempted to submit a clean-up patch 
for TCX too when this is complete just to keep both drivers in a similar 
state.

One thing I'm not sure about is how the QOM stuff interacts with sysbus 
- can you quickly point me towards an existing device that does this so 
I can understand how this works? These patches have been around for 
months and I really want to get them in for QEMU 2.0 if freeze is coming 
up soon.


Many thanks,

Mark.
