I know it exists because two people on Audiosurf have it. Unable to contact them, though...

Anyway, like the title says:
Game: I/O (PS2)
Song Name: Fragment
Song Length: 5:00+ (THIS IS THE IMPORTANT PART)
Artist: ONOKEN.

The short version is widely available, but the long version is practically impossible to find. Any help on this?

Got an extremely lucky break, and found it, along with the entire I/O Perfect Soundtrack.
