With lastest acpi I had to patch the acpi_os_table_override and not the acpi_os_initialize function as it was the case before to include my own dsdt table. I've attached my dsdt.hex file for Compaq Presario 2818, it should work with all the 2800 family. All work now (even suspend on disk, but still problems with some modules at wake-up).
Thank you very much for having included a functionnal acpi on mdk kernel, this
is very helpfull to my laptop which was still a Windows addict, only for
power management (which is most than important on laptops).
Regards,
Sebastien.
