What you describe is one of the few complaints I have with Apple. Come-on, just put the full download on the stupid site! Having to dig-up your system discs, install a version of BC drivers you *know* is old and buggy, and then upgrade them with a partially-functioning download from the Apple site is just plain retarded. I *hate* having to install older versions of something only to follow some "upgrade" path like that. Just let me install the new ones from the start! Grrr
BTW, this is the same behavior that led me to detest Creative Labs as they used to make you install from the CD included with the soundcard, and then go "patch" with drivers from the site. To this day, it's been probably 8+ years since I paid for a Creative soundcard, maybe longer.
OK, getting off my rant-horse now...
