I've installed
Linux piBook 3.9.0-030900-generic #201304291257 SMP Mon Apr 29 16:58:15 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

now the high cpu load and dmesg spanning is gone, it looks like the device is 'propely' blocked now (even though the hardware switch is set to enable wifi, but the device is a bit old, so I guess the switch isn't always working properly anymore).
So this issue is fixed by switching to the latest upstream kernel.

However, when I plug in a USB wifi device, I still can't enable it
$ rfkill list
