The/. summary makes it sound like all Power/iBooks are experiencing battery drainage after updating to 10.2.4 - my 2002 600 mHz iBook updated just fine, and battery life is the same.

Ditto for one such iBook and two different 15" PowerBooks here (mine and those of my coworkers). No issues whatsoever with 10.2.4. Furthermore, 10.2.4 patched a nasty bug that caused laptops running 10.2.3 to kernel panic about 1/5th the time a user logged out from the desktop.
I'm a little surprised that the linked MacFixit article had no suggestions about resetting the Power Management Unit [apple.com] for affected users.
As with a lot of computer problems, not everyone will be affected.
I can tell you, though, that my 500-MHz Ti got its battery kicked in the nuts immediately after 10.2.4.
Apple is sending me a new one (yay AppleCare), and the word is that they're on back-order. (Yay for being a service provider... Oh, wait, I still won't get my battery before anyone else.)
If you do suspect your battery is hosed, CALL APPLE. The more reports they get, the sooner it will be acknowledged officially. Prevent future Q&A problems today.:-)
My battery is just over a year old, and I haven't noticed anything unusual since moving to 10.2.4. I'm pretty hard on my battery, too - never shut down except to reboot after upgrades, rarely take my battery below 50% charge.
I haven't noticed this on my iBook, really, a 2001 Rev A white iBook. I say "really" because I'm only getting a few days life in sleep mode, where I used to get about a week, but I assumed that was because I recently changed my sleep settings.
My 1 month old iBook 800 (12") also has no problems. You may also want to try the script poster by a reader at macintouch [macintouch.com], it gets the status of the battery from the ioregistry.
FWIW, the output on my 88% charged iBook 800 (12", combo drive, november '02 model, bought in Januari) is voltage=11928 flags=4/0x004 amperage=1023 capacity=4192 current=3692 [88.1%]. I can squeeze 5+ hours out of this (just typing text, screen dimmed to the one but darkest setting, cpu speed set to "automatic"), so the battery is definitely good. I don't know what normal or good capacity values for other models are.
