I have a Microsoft Sculpt Bluetooth keyboard. On Linux, it does this. On OSX, however, it still takes a few seconds to wake up, but the keystrokes typed while 'waking up' do make it through to the screen in the right place. I keep meaning to dig into the Linux Bluetooth stack to see if those initial keystrokes can be salvaged. I guess they're sent in a burst once the keyboard realises 'yeah, I'm being typed at', but Linux seems to ignore them for some reason.
