To clarify: it is not necessarily that a property is disallowed; what will
happen is is that a style change between a:link and a:visited will be ignored.
To give an example:
a:link {border: 1px solid; color: blue;}
a:visited {border: 1px dashed; color: red;}
the change in border-style (from solid to dashed) will be ignored,
border-style:solid will be used for a:visited.
I made a small test file with a couple of examples along the lines of the
above. Included in the folder are 2 screenshots, the one labeled 'webkit' is
taken with the latest nightly build of WebKit and is affected by these changes.
The one labeled 'Gecko1.9.2' is taken with the current release of Firefox 3.6.3.

It is a work in progress. I may add more examples, depending on inspiration or
the weather or …

Oh, but you still have lots of possibilities...
a:link {color: yellow; background: red;}
a:visited {color: red; background: yellow;}
