--- Comment #12 from Dan Kegel dank@kegel.com 2008-04-16 14:34:21 --- Adobe's download help document says they use the Akamai download manager for all files larger than 1GB. Maybe they've lowered that number recently.
When I went to that link, it happily automatically started the download manager; it's a Java applet. So install / enable Java on your linux box, make sure you can run applets, and you should be fine.
(Last resort: in bug 11719, which also involved the akamai download manager, I found that the real URL was left behind in a data file -- at least if you were installing inside wine. )
