Nope. First, this considers files to be the same as directories.
Second, this only excludes CVS directories from the top level - deeper CVS
directories are included.
Suffice it to say this series of attempts indicates that find/etc is
NOT a reasonable(*) way to implement this (reasonable) request.
Add the argument to du(1).

(*): since no one here in what should be one of the most experienced group
of BSD hackers has posted a workable "unix-style" method, I conclude
that it's either not possible, or at least is so non-obvious as to be
effectively non-existant to any but the most experienced user.
That's the problem with the old-school Unix philosophy of no program doing
more than one thing, and stringing them together - the "stringing them
together" part often ends up being as complicated a task as programming a
solution into the program itself - or even more complicated. That's ok
(sort of) if everyone using it is a programmer, and doesn't mind
reinventing the wheel every few days. It's not ok for 99% of users.
Sure, shell's are programming languages - but I don't really want to write
a program just to find out how much disk space I'm using, or to sort the
output of ls (another old argument), etc.
ps. yes, I am a shell-script hacker to a degree, and have written shells,
and used shells in all sorts of evil ways - but I don't want to tell
everyone else to try to do that.
