No it doesn't show up in the bonus account in cashier.
Here's the email I got in response to basically asking the same question I originally posted here:
Thank you for contacting Full Tilt Poker
To qualify for this bonus players have to earn 50 FTPs (Full Tilt Points) at the Rush Poker tables according to the timeframe stated in the pop-up. You are immediately opted into this promotion once you receive the pop-up offer so there is no need to click anything in order to activate the offer.
Full Tilt Points (FTPs) are reward points you accumulate every time you play for real money
You earn 1 point for every dollar raked in a live cash game up to 3 points per hand.
Unfortunately, Full Tilt Points (FTPs) earned through our Happy Hour promotion are considered bonus points and do not count toward other promotions unless specifically stated.
Please remember that it may take up to 24 hours after completion before your account is credited with the $25 bonus.
Thank you for playing at Full Tilt Poker. If there's anything else we can do for you, please let us know.
