I have used this tutorial for both the Mini 9 and 10v. Both worked the same with the exception that the setup screens for OS X were beyond the bottom of the screen. I had to experiment with using the tab key and the space bar until I finally got the installation on the go.
When you first boot the 10v in OS X it will only let you see 640x480, but once you finish the Engadget tutorial steps you will be up to 1024x576 instead of the 1024x600 that I have on the 9;
Also you have to download a different sound driver. So far, everything is working except the internal microphone. The side jacks work just fine. The 9 has a better amplifier.
Both the 9 and 10v install from a non-modified retail OS X installation DVD and work with standard upgrades from Apple. So far I haven't found any software that doesn't require a dual core processor that won't install on either unit. The keyboard size and layout is much better on the 10v.
I am still looking for a better sound driver for the 10v. Other than that I am happy for the slightly larger size and bigger hard drive. This next week I am going to order a RAM upgrade and Bluetooth. I just added Bluetooth to my Mini 9 this last weekend and it all went swimmingly.
I am satisfied with handing down the Mini 9 to my wife and stepping up to the 10v.
