Here a few comments where I've elaborated on François' suggestions:

                             - Doesn't the current validator already  
do this?

                              -  It would be useful if the validator  
could determine which vendor-specific prefix related to which browser  
and display the result (i.e 'We have detected that you are using a  
property that is specific to, and can only be read by [browser-name]').

                        - Can't help but think this would take quite  
of effort to compile information for all hacks used by each individual  
browser? If this feature was implemented, which browsers would we  
include in this matrix?

                              - The examples you specified are still  
both valid CSS selectors, (although the markup the selectors relate to  
would be invalid HTML). Also, your feature would be doctype dependant,  
so would be a feature specific to validating against a URI of an  
external HTML document as opposed the stylesheet itself.
