There are at least two different upload baud rates in the boot loader, depending on your version
Sanguino software from [code.google.com]
Versions Sanguino-0023r4.zip and up use 57600, eariler versions use 38400.
You should be able to edit your boards,txt and change upload.speed= as needed. (not tryed)
If I find it easyer to just reflash the bootloader with a 57600 version, then I know what it wants.
Fuses set hardware parameters, including baud rate devisors and boot options.
The following is very useful if you have to play with these. [www.engbedded.com]
