Have you tried p7zip? You probably want the p7zip-full package. I haven't 
tried splitting archives with it before, but it should work. I don't think 
the GUI version of 7-zip runs on Linux.

What version of zip are you running and are you on 32-bit or 64-bit? If 
you're running zipsplit on 64-bit, it shouldn't have that limitation. That 
may be a limitation of the zip standard, in which case you're out of luck. I 
think that version 6.00 and up of zip should have large file support, but I 
also remember that it might not support the zip64 spec used by WinZip and 
other tools on Windows. I recall reading that zip 7.0 might support zip64 
archives, but I think that's on the todo list and who knows if or when that 
will happen. Another option might be funzip. You could try filtering each 
archive into zip and creating new, smaller archives.
