If anyone has any objections, please let me know. ------------------ From: Szilard Fabian [ Upstream commit 4255447ad34c5c3785fcdcf76cfa0271d6e5ed39 ] Another Fujitsu-related patch. In the initial boot stage the integrated keyboard of Fujitsu Lifebook U728 refuses to work and it's not possible to type for example a dm-crypt passphrase without the help of an external keyboard. i8042.nomux kernel parameter resolves this issue but using that a PS/2 mouse is detected. This input device is unused even when the i2c-hid-acpi kernel module is blacklisted making the integrated ELAN touchpad (04F3:3092) not working at all. So this notebook uses a hid-over-i2c touchpad which is managed by the i2c_designware input driver. Since you can't find a PS/2 mouse port on this computer and you can't connect a PS/2 mouse to it even with an official port replicator I think it's safe to not use the PS/2 mouse port at all.
