Of course you can do what you want in your style file. I know, that most mappers don't fully understand the OSM access system. ;-)

I still don't agree with you. In the potlatch editor, you see this screenshot when you are filling in the access rules. There is nothing said about access for cars on footways, so I assume the general access rule is already based on the highway type (which can be slightly different in each country).
The real question is what access=yes means.
A mapper who fills in this edit form (highway=footway, general access permissive) is according to mkgmap opening this way for cars. (highway=footway, foot=yes, access=permissive, so access could not set to no)
Just because potlatch does something doesn't make it right or wrong. We have to figure out semantics.
So my opinion stays, in case of access=permissive, don't set this to yes but delete the access rule otherwise you are ruining the routing.
That's adjusting mkgmap to interpret tags according to semantics that match how potlatch is, which skips the step of understanding and getting agreement on the tagging semantic. It's pretty clear from http://wiki.openstreetmap.org/wiki/Key:access that access=yes "describe[s] a general access restriction that applies to all transport modes." So highway=footway access=permissive indeed means that the way is intended principally for foot traffic but that one can use cars, horses, and bicycles. Potlatch should be setting foot=permissive instead; this probably needs to be brought up on tagging@ or talk@ because there has to be broad agreement about what tags mean among mappers, editors, and data consumers.
