It is.. it is there for people that need to test it works on their system
before they use it on a system they /need/.
As you can see it causes problems on some machines where it interacts with
the drivers in a bad way.
Now you have done the test and found it to fail you need to wait until Dell
fix the drivers before you can install it.

Personally I wouldn't have put Vista on an XP machine I was using for work.
I would buy a new machine with Vista on but I can't see any compelling
reason to upgrade an existing machine that works. The same goes for any OS
and machine combination IMO.
The old "if it works, don't fix it" applies to computers as much as anything
else.
