For perks, you search for the number of perks you've spent so far. So assuming you have 6 perks to spare, you'd buy one perk and search for "1", you'd buy one more perk and search for "2", and so on, until you've spent all your perk points and are left with a single 4-Byte value of "6", assuming you spent all your points.
When you change that 4-Byte value to 0, you'd have 6 new points to spend. If you change that value to -2, you'd be left with 8 points to spend.
Of course, the crux of the matter is that in order to actually perform this search, you need something along the lines of ~3-5 perk points already, which makes it impossible to add perks when you'd want to - early in the game. And you'd have to not spend perks at all for many, many, many levels. And you can't find the 4-Byte value in one game and then load a save, because that will change it.
There must be a better way to find the correct value, but I sure as hell don't know it. Incredibly frustrating.
There also appears to be no way to use the in-game console to add perks or perk points.
