I can also confirm that you can downgrade a 160GB 1.1 to 1.0. The online instructions are still a little confusing, but following a few different guides I was successful in "upgrading" my 1.1 AppleTV to a "safe 1.1" (modified 1.0) version. There are a few holes which hopefully I can patch up for you here.
These are the most useful sources:

Downgrading preinstalled 1.1 AppleTV to 1.0 - CONFIRMED METH (http://forum.awkwardtv.org/viewtopic.php?f=13&t=839&st=0&sk=t&sd=a#p4868)
- the Readme.txt in the Patchstick.zip
Before you start, you'll need:
- Intel Mac running 10.4.* (Leopard doesn't work. Make a temporary new partition and install Tiger). 10.4.9 seemed to work best.
- USB Drive: 500MB or 1GB (I used 1 GB and it worked fine)
- The .dmg file for Intel Combo upgrade to 10.4.9 (from apple.com). 10.4.10 is ok too...
- the patchstick file
- both OS (.dmg) files for Apple TV: 1.0 & 1.1
MOST OBVIOUS (OR NOT): you're going to patch your Apple TV *twice*. The first patch affects 1.1, which doesn't allow you all of the useful features, but it give you just enough (SSH) to talk to your Apple TV and copy over the OS 1.0. Once 1.0 is installed, then you'll repeat the patchstick process (i.e. to patch the new 1.0).
Creating the Patchstick
Unfortunately, you'll run into a few hurdles in creating it, so be patient. Most common are:
- the USB stick has to be a certain format
- you may need "root" permission
Both of these hurdles can be resolved via Google as they apply to other tasks as well (i.e. creating a USB OSX boot disk).
Applying your Patchstick
Plug it into the back USB port. Then on your remote, hold down the Menu & minus buttons. You'll want to hold them down for several seconds - long enough for UNIX text to appear. If you see the opening video montage you didn't do it long enough, so try again.
How to know when the patch process is complete
This part can be confusing. The instructions mention waiting for your Apple TV to restart several times. However, if you don't recognize your "cue", it will restart forever.
The correct time to remove the USB stick is when you see the words "All Done!" (or similar) in the displayed text. You'll probably also see "Restart in 30 seconds..." Note that these messages might not be the last rows of text - they may just be close, a few lines up perhaps.
At this "cue", pull the USB stick out (yes, while the ATV is still running). Power off your Apple TV (unplug the power cable) and plug it back in. Once the menu finally appears, you should be able to see "Awkward TV" in the menu.
Avoiding the Auto-Upgrades
Ignore the "manual process" presented in the Beginners Guide; it's much easier to use nitoTV instead. NitoTV will enable several things for you, including:
- grabbing necessary parts from 10.4.9
- create a "safe 1.1 OS"
- take care of that pesty Auto-upgrade problem
NitoTV doesn't do these automatically: use the nitoTV menu and follow the instructions.
Good luck!
