It must have just gone down recently, as judging by various google results shows that the link was live as late as mid-november 2008. I wasn't able to find anyone that had a copy of the files available on the web anywhere. The only other *nix option for the 780 would be
netbsd. Also, the linux packages that were on the handhelds.org site contained a kernel version that was pre-2.4. It might be worth trying to create a new build using at least a 2.4 kernel.
