I highly doubt that _the_ Stig is Lewis Hamilton, considering several things. 1) The white Stig has been around since the start of season 3, which aired in November 2003. Lewis Hamilton would have been 19 at the time of filming. Highly unlikely the BBC would let a 19 year old, no matter how talented, hoon around in such cars as a Gallardo. 2) By looking at the gap between his racing suit and his helmet, it has been determined that (at least sometimes) the Stig is a white male with dark hair. Lewis Hamilton is a dark-skinned male with very short shaved black hair 3) When Hamilton did he F1 Star in a Reasonably Priced Car drive, he was only 0.3 seconds slower than the Stig's time, and on a wet track too. It is generally regarded that a wet track is 2 seconds slower than a dry one, thus Hamilton is 1.7 seconds faster around the track than the Stig. 4) According to one of the stunt drivers on Top Gear, the Stig is not played by one person. Thus, it _could_ have been Hamilton, but definitely not all the time 5) Stig does speak, but never on camera. Thus, it would be expected that a very high profile F1 driver, who often speaks on camera, would not be a good choice for the Stig when he is coaching the celebrities.
