The "Greenland" was just an example of the boosting already taking place, and I put it because its quite obvious that boosting was taken place, while other places it might not be that obvious. On starts with lots of water, it is typical for the map generator to put extra seafood. And if I'm not mistaken, the booster will also place (small) rivers on bad starts, to balance them.
The "Greenland" example shouldnt happen anymore. It was a screenie of a Puritan mod I made for those people who like to play by civ vanilla rules, but also wanted to try 34 civs on bigger than Huge maps.
In an earlier version of VIP I did lessen both ice and tundra, and was surprised that it was back to default, but I can assure you it WILL help with that adjustment.
What HAVE bugged me (and a lot of other people) is the river starting positions. Quite a few civs started near river deltas or at the source of rivers, but the source of a river in civ IV is not technically a river, and I would love to fix that.
Giving all civs the same('ish) startposition would be fair, but imho also a bit boring as the exploration (and later capturing) of enemy civs capital would be bland, but if I'm not mistaken that is what the "Balanced" mapoption will do (I havent tried it though).
Regarding the individual placement of civs near their "habitats" i.e. seafaring near sea, would, for me, be impossible to code.
But if you look at the above 34 culturally linked starts screenie, then you'll see that there isnt a single ice or tundra start
