Basically, the idea was to make a character pay for the starting
augmentation with an XP penalty, like that used in creating a magic
item. As far as I can tell, a negative XP level is possible without
causing penalties; it would simply *imply* you need that much more to
reach level one.

You could do this. Create a "new" XP chart.
For instance, if you require say an initial 2,000 XP before the
character can become "level 2", you could create the chart like this.
Character
Level XP
1 0
2 3,000
3 5,000
4 8,000
5 12,000
6 17,000
7 23,000
8 30,000
9 38,000

This is completly acceptable, as the player/DM would still have to rely
on another source (ie PHB) to use the table properly. If these enhanced
characters simply have an XP penalty (such as 10% of all XP is lost),
you can simply state "because the characters enhancements help the
character out so much, by making tasks easier, he doesn't learn as much
as a normal person relying on their own natural abilities might.
Because of this 10% of all XP the character gains is lost".
