Here's somethign that struck me which hasn't ben mentioned yet:
Max skill ranks = level+3, right? So, skill ranks for class skills could be something like the following:
Low levels:
At low levels (levels 1-6) all of your class skills are all treated as having your levels' ranks in them. For every point of Intelligence bonus your class skills are treated as one step higher (or, level +1, etc) up to one step higher.
Non-class skills are treated as having your level-6 ranks (with a minimum of 0) ranks in them. For every point of Intelligence bonus, your non-class skills are treated as one step better (or, level -5, etc) up to level -5.
A low Intelligence will treat lower your ranks in both class and non-class skills by up to 3 levels for every point of negative Intelligence modifier.
Middle Levels:
At middle levels (levels 7-12) your class skills are treated as having your level+1 ranks in them. For every point of Intelligence bonus your class skills are treated as one step higher (or, level+2 etc) up to two steps higher.
Non-class skills are treated as having your level-5 ranks ranks in them. For every point of Intelligence bonus, your non-class skills are treated as one step better (or, level -4, etc) up to two steps better.
A low Intelligence will lower your ranks in both class and non-class skills by up to 2 levels less for every point of negative Intelligence modifier.
High Levels:
At high levels (levels 13-20) you class skills are treated as having your level +2 ranks in them. For every point of Intelligence bonus your class skills are treated as one step higher (or, level+3, etc) up to three steps higher.
Non-class kills are treated as having you level-4 ranks in them. For every point of Intelligence bonus, your non-class skills are treated as one step better (or, level-3, etc) up to three steps better.
A low Intelligence will lower your ranks in both class and non-class skills by up to a level less for every point of negative Intelligence modifier.

It's kinda messy, kinda complicated, but it works, I think. It also includes Li's mention of how any of the previous incarnations of this do not include Int mods, etc.
I realise at high levels, my system actually makes class skills+a high Int mean that you can have some
really high mods, but isn't that the point of being nearly
EPIC level? Wizards know dark secrets from the beginning of the aeons, Swashbucklers have the greatest wits around, etc? Personally, having a potentual +2 points higher in class ranks for your skills is not that big of a deal, and hell, you could treat those bonuses which are greater than your level+3 as a specific bonus type (like insight, etc) if you really want to get nitty-gritty.
The design was that lower-level guys should have a harder time of it; negative Intelligence penalties are going to hold you back, and only marginally increase your potential. At higher levels, a low Int won't hold you back as much while a high Int will really allow you to reap the benefits.
Well, hope that made sense; it took about 20 minutes to come up with
cheers,
