U'll need a High-Voltage parallel programmer to unlock a serial disabled AVR, I'm not sure about HV-Serial programming though but the 1 below does the job.

In fact there are various easy ways to unlock an AVR written with wrong fuses. Many enthusiasts have tried and suceeded in the ways they found convinient, including me. I have suceeded in the trick mentioned by "   " on the third page of EDA board thread found here. "http://www.edaboard.com/ftopic323123-90.html"
Sorry...that the link given is almost the same thread, but may be a different page as i have given it from my offline contents. While i was posting this, i coudnt acess the EDA board website. may be some technical server problems.

Here is AVR fuse bit doctor. It reset fuse bits to default. No PC needed. Just Plug & Reset

@jeckson: In case u experience a bricked AVR problem u'll need a HVPP programmer to unbrick it, afaik HVSP won't be helpful in that case. The 1 I posted in my first post in this thread can make both HVPP and HVSP, AVR Doper is only capable of HVSP. Ur choice but I've actually made both of them and they both do their jobs well.
