"I don't think I've ever been this excited about something, which might say something about what my activities (or lack thereof).
What I did was I installed the Mac OS X 10.4.5 8G1454 IOUSBFamily.kext 2.4.0 System Update for iMac with Intel Core Duo and MacBook Pro. The file can be found here:
http://developer.apple.com/hardwaredriv ... debug.html
Download the 'v 240.4.3' file, run it, and install the package that DOES NOT have the '-log' ending. That is, run IOUSBFamily-240.4.3.pkg and NOT IOUSBFamily-240.4.3-log.pkg. Restart your computer, and the whine will be gone. You do not need to run photobooth or do any known workaround to quiet it down...
Also, I think you might need 10.4.7 installed first. It is not an installation requirement, but I believe it is a requirement for the fix to work
EDIT:
Eipä tämäkään fix näytä aivan kaikilla pelaavan, mutta jos rohkeutta riitää ja sirinä ns. hatuttaa niin kannattaa kokeilla. Täällä auttoi

EDIT2:
Whine on edelleen poissa, mutta huomasin ettei näppäimistön taustavalo enää suostu menemään päälle tämän asentamisen jälkeen. Ongelmasta selviäisi asentamalla 10.4.7 IOUSB, mutta sirinä tulisi takaisin, joten näin mennään.
