John Pinheiro, here is my answer from a similar question: How to I fix my disabled iPod Touch? Apple says, "If you cannot turn off the device using the slider, press and hold the Sleep/Wake and Home buttons at the same time. When the device turns off, release the Sleep/Wake and Home buttons." Now there is a way to erase the password, but I am not sure if this would work when you are already disabled. I guess you can always try and hope you have a Windows computer :-) Anyhow, you plug in your iPod. Open My Computer (or Computer for Vista). Click on Folder options and enable to view hidden files. Next, go to iPod_control and click on the folder named Device. If your iPod is locked, there will be a file _locked. Rename the file to _unlocked. Remove your iPod and it will be cleared. Again, not sure if it works for a disabled one. Just thought of something else. Make sure you have your library backed up.

Also, check what Apple has to say about that on here: http://support.apple.com/kb/HT1808

You can also try to use recboot available here which possibly gets your device into recovery mode.
