I can confirm that the lapdock does indeed work as a hdmi monitor and usb mouse / keyboard, I had some spare time and tried it out.
I just spliced a USB A to a micro USB female, works great on my ps3. I just connected USB Rx Tx and ground, Don't bother connecting USB +5vdc red as it sends power up stream and may damage whatever your connecting it to.
here's a video of it in action.
I sent an email to sparkfun inquiring about a micro hdmi female breakout board and here's they're response:

Thank you for your breakout board product suggestion. You bring up a great point about seeing this type of connection more and more. I will forward it on the appropriate people to see if this is something we can make and carry. Thank you again and have a great day!
Hopefully we see something from this.
