Strange behaviour

[Felix Oxley]

Fedora 9
powertop 1.9
FireFox 3.0b5

When I log on powertop shows <150 wakeups per second
If I start Firefox at homepage this does not change.
But when I type the address of a page (and press enter) wakeups goes up to
>5000 /s
After that it remains high (>5000) even if I close FireFox
