No, their "i386" doesn't actually mean 80386:

However, Debian GNU/Linux wheezy will *not* run on 386 or earlier
processors. Despite the architecture name "i386", support for actual 80386
processors (and their clones) was dropped with the Sarge (r3.1) release of
Debian<http://www.debian.org/releases/stable/i386/ch02s01.html.en#ftn.idp5578656>.
(No version of Linux has ever supported the 286 or earlier chips in the
series.) All i486 and later processors are still supported.
