The problem was related to ACPI DSDT. In dell 5748 BIOS puts keyboard resources on the PS/2 mouse port. I fixed the problem with a DSDT table dump and a simple patch that moves I/O port, 0x66, for PS2M (the mouse) out of keyboard CSR. After that, I compiled a new AML code for the DSDT and loaded them using the boot loader vars below: acpi_dsdt_load="YES" acpi_dsdt_name="/boot/dell_5748_deftunix.aml" If someone is interested in patch and/or my AML DSDT send me an e-mail. Who should I contact for develop something more useful and versatile like as atkbd, pcs and apci kernel modules patches?
