[devel] Проблемы в работе точпада на Branch5

Всем привет

Обновил на Net-буке Branch 4.1 до Branch 5.0 и обнаружилось, что 
тамошние иксы перестали корректно различать точпад.
Точнее они различают, но одновременно видят точпад и как обычную мышь. В 
результате на одно устройство вешаются два драйвера или два протокола. 
Как отрицательный эффект этого безобразия точпад стаёт раза в два 
медленее, двойной клик и прокрутки выключаются. Эффект от gsynaptics 
отсутствует, хотя доступ и есть.

Кстати подобный эффект наблюдался и на Branch 4.1 с другой моделью ноута.

Ниже привожу сравнение участков логов с обнаружением мыши и вкладываю 
конфиг:
