Tsaeb, this was no brain teaser at all. Here are some points to remember about IRS regulations:
1) If the 2001 tax year publications are the most recent offered by the IRS, they're as good as law. If the 1405 BC tax year publications were the most recent, they'd be as good as law. (Don't expect the new ones until December.) Sometimes you can get hints of the new regulations on the home page or home page links of
www.irs.gov.
2) People who do not itemize deductions cannot deduct charitable contributions. They are understood to be covered by the standard deduction. Since the non-itemizers don't deduct the contributions, they don't get the carryover, either. (Of course, charitable deductions can be taken by a business, but not on Schedual A.)
3) If non-itemizers are ever allowed their own deduction for charities, disregard item #2 above.

With the IRS, everything is subject to change.
4) Very few people ever use this carryover unless they've given things like cars or machinery or property (one-time large gifts). There is very little tax incentive to give gifts. I always tell folks, make sure you're giving out of the goodness of your heart; the monetary benefit just isn't there!
