на счёт клавиш незнаю - на Chicony KB9885 xev фсё видит, тока config клавы подрихтовал.

Посмотри на gentoo-wiki.com. Некоторые клавиши по дефолту ядро не видит и надо ему объяснять, что стоит их обрабатывать (проверяется просмотром dmesg). И совсем странные кнопки можно ловить чем-то вроде photkeys (кажется так называлась.)
