I solved!
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?
Thanks,
-- Mauro
