I think I may've done the same just today....  I had a simple EPROM/Parallel EEPROM reader sketch loaded, using the upper digital pins (D22-45 as A0-A23, D46-D53 as D0-D7 ).. Using the Linux X64 version of 1.0.6, it was getting all kinds of extraneous data (supposed to dump in 16-byte blocks, but lines were showing up > or < 32 character length)
at 115200 baud, so I wanted to slow it down.  Okay, Except.... as long as the device was printing data to the serial line, it refused to allow loading until it finished printing. (out roughly 256K of data)..  So, I tried pushing the reset, to see if I could force it into standby, to await for the IDE to load the new sketch (this time slowed to 57600),... Suddenly,
 
Code: [Select]
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout
avrdude: stk500_2_ReceiveMessage(): timeout

  repeating until I closed the window.  
I tried the device on the Windows-Laptop..  recognized device, Serial port 29, but...  no response...  connected a wire between D0 & D1, It was echoing through the serial port, but....  nothing form the 2560 itself...

 I haven't read through the entire thread here, but is there a way to check if I fried the 2560, bricked it, and can it be unbricked? or am I in the market for a new MEGA? Pretty sure it's _NOT_ a Rev 3 MEGA2560....
