I have modified the standard bootloader to work on the 2560 mega.


http://www.cbxdragbike.com/arduino/bootloaderdocs/index.html

One important note, it only supports 128K bytes because the stk500 v1 protocol only supports 128k bytes.

Also, there is a bug in the gcc 4.3.2 compiler that really limits you to much beyond about 80K program space. This if fixed in gcc 4.4.0 and later.

I am working on an stk500 v2 bootloader for the 2560.

Funny you should bring this up I was just looking at one today.  You might want to check out eMartee at www.emartee.com.  They sell the board and have a post on how to get the bootloader, as a matter of fact they have everything on thier site.  I was logging in to ask if anyone had dealt with this company before I placed my order for one.
