Using an OS that predates the release of your machine usually does not work due to driver issues the guys have mentioned. Whether it will work or not depends on how different your hardware is from the hardware that had Lion drivers. If you want to try going backwards here's what I would do assuming that your current Mac installation is stable and working well:

1. Clone your current installation to another hard drive. You will need a drive slightly larger than your Mac's current drive. I suggest using Carbon Copy Cloner because it copies the recovery partition correctly.
2. If the clone does not include your data back that up as well if it is on the main drive.
3. Clone your Mac to the second hard drive. When that's done boot from the clone and log in to see that things are ok.
4. Install Lion and test to see if things boot properly. If not you can use your clone to restart and clone things back to the internal drive to get back to normal.
