I just answered this question in the Guru forums. Here's what I said there:

Yes the rules still apply in those situations. However, there are a few loopholes to Reg Q. ยง217.101(b) states:
Notwithstanding paragraph (a) of this section, any premium that is not, directly or indirectly, related to or dependent on the balance in a demand deposit account and the duration of the account balance shall not be considered the payment of interest on a demand deposit account and shall not be subject to the limitations in paragraph (a) of this section.
If the "bonus" is not related to the balance in the account AND the duration of the account, you can pay any amount you want. Keep in mind IRS 1099 issues as well as Reg DD bonus issues if you promote these "bonuses".
