The source (for the latest version) is freely available on the Atmel
site: http://www.atmel.com/dyn/products/tools_card.asp?tool_id=4093

If you really need the source for an older version, I'm sure the Atmel
support will send it to you upon request.

Did you try disconnecting the battery ? Or replacing the battery with a
new one ?

See above.

AT91Bootstrap seems to be at v1.9.

As for U-Boot, try the latest git (which will soon be u-boot v1.3.4).

(BTW, if Wolfgang is listening, it would be nice to have proper tags in
git as well as releases on the ftp server for the -pre version. Since
the merge window is closed, I guess we're up to v1.3.4-pre1 now, but
this version tag cannot be found anywhere...)
