I _know_ they have this far only studied brains and normal detached cellblobs.
What has NOT been studied, how a cellular phone in a front pocket of ones trousers having GPRS/UMTS/WLAN-connection somewhat active affects testicles, prostate, ovaries and such in a long term.
We may have lots of cancers coming in the future years and everyone hits their forehead ....uhhh we didn't think about data-connections in the trousers at all.

Wow!
That would explain my massive penis.
(I'm going to put another mobile phone in my pocket)
It's the same energy pulses that interfere with speakers/amps that would get misintepreted as data and set your capslock on/off when you put it close to the antenna called keyboard cable.
The N900 does of course, like any transmitting device, send out radiation in the form of radio waves. This is totally normal and subject to very strict SAR testing and regulations before phones can go on sale - so you don't need to worry on that front.
Without going into the physics too much for the particular scenario which this thread suggests... the power level of a transmission (which is not narrowly focussed to a point) which could spontaneously cause an electrical arc in a membrane circuit - even with some radiation being conducted down a keyboard cable (which would act as an aerial) would have to be well above safe SAR levels and also totally unnecessary for mobile to mast communication.
It is more likely that due to a fault or poor design that your keyboard's controller circuit is susceptible to radio interference and this is distorting real/phantom signals in the keyboard controller's circuitry and falsely acting on them (as you claim by flashing caps on and off).
You don't need to worry about it, is the long and short.
i'm 90% certain it'll be magnetism rather thanradiation causing this. there are magnets on/under the kickstand. try a normal magnet on the keyboard wire.

I've just checked... The N900 has a SAR value of 0.8 W/kg which is in the middle of all devices I've seen. They go from 0.2 W/kg to 1,9 W/kg. The maximum in Germany (and I guess most other regions) is 2 W/kg.

I've quite a good knowledge about how this physically happens. But I just never thought a mobile phone could send that strong...
However, I have already seem similar behaviour with an ethernet Cat5 cable and an IR receiver. While transferring data over the ethernet cable laying next to the IR receiver, the receiver's LED was flashing. I wass searching about 15 minutes for a remote control someone must be sitting on
So thinking a bit further I guess if the ethernet cable is capable of doing such things, a mobile phone transmitting data over the air for a relatively long distance can easily screw up weak keyboard controllers...

Don't think so... This doesn't happen when there is no data connection... However, I agree the kickstand's magnet could support this behaviour...

Sounds right. The N900 is not the strongest radiating phone I've had. We use comm headsets at work and for awhile they banned cellphones because they interfere so much.
My N95 8GB interfered with my headset MUCH more than my N900 does.
