Oh, thanks but luckily not. The missed first keystroke was about 3.2/3.3 series and I know I was not the only one. I don't have the problem now, with recent kernels. And the mouse going sleep ... I think it is my ignorance to configure kernel on the fly, or use the laptop-mode-tools to do it. I just haven't settled on a single power management tool. cpufreutils is now obsolete, I have some issues with laptop-mode-tools ... but, no, no kernel bug to report at the moment. Don't worry. ;-) I believe I can prevent mouse falling a sleep once I find where do I have to send the echo with it's USB ID if I don't go the laptop-mode-tools direction. But it is only an issue for me when on battery, so not urgent.
