Ah.
I was wrong on this. My prior reading was that author overrides user,
_including_ in use of the "!important" attribute. I see this isn't the
case. As this is a change from CSS1 I may have been confused by prior
references or different sources.
This is a much better situation than I'd feared. Spec follows.
http://www.w3.org/TR/REC-CSS2/cascade.html
Cascading Style Sheets, level 2
CSS2 Specification
W3C Recommendation 12-May-1998
6 Assigning property values, Cascading, and Inheritance
...
6.4.1 Cascading order
To find the value for an element/property combination, user agents
must apply the following sorting order:
...
2. The primary sort of the declarations is by weight and origin:
for normal declarations, author style sheets override user style
sheets which override the default style sheet. For "!important"
declarations, user style sheets override author style sheets
which override the default style sheet. "! important"
declaration override normal declarations. An imported style
sheet has the same origin as the style sheet that imported it.
...
Apart from the "!important" setting on individual declarations, this
strategy gives author's style sheets higher weight than those of the
reader. It is therefore important that the user agent give the user
the ability to turn off the influence of a certain style sheet,
e.g., through a pull-down menu.
6.4.2 !important rules
CSS attempts to create a balance of power between author and user
style sheets. By default, rules in an author's style sheet override
those in a user's style sheet (see cascade rule 3).
However, for balance, an "!important" declaration (the keywords "!"
and "important" follow the declaration) takes precedence over a
normal declaration. Both author and user style sheets may contain
"!important" declarations, and user "!important" rules override
author "!important" rules. This CSS feature improves accessibility
of documents by giving users with special requirements (large fonts,
color combinations, etc.) control over presentation.
*Note. This is a semantic change since CSS1. In CSS1, author
"!important" rules took precedence over user "!important" rules.*

Peace.
