[ACPI] Error overriding DSDT table

[Leonardo M. <macchia@CS.UniBO.IT>]

Hello.

I'm trying to patch the DSDT table in 2.4.19's ACPI but I get some
errors. I have a Compaq Evo N600c.

I applied acpi-20020821-2.4.19.diff patch (and if I stop here the kernel
works... but I can't see any battery nor fan resources) and
linux-2.4.18-acpi-20020709-dsdt.patch.
With acpidump I got the original DSDT table where I changed the wrong
entries

Name(_HID, "*PNP....")

into

Name(_HID, "PNP....")

so I used iasm to create the hex file from the patched table... I got
some errors ("Object does not exist" and similar) but I've heard to
ignore them... so I moved this hex file into
drivers/acpi/tables/acpi_dsdt.c and compiled the kernel.

After starting the kernel, ACPI results disabled (no /proc/acpi) and the
kernel - during boot - says:

[...]
ACPI: Subsystem revision 20020815
PCI: PCI BIOS revision 2.10 entry at 0xf04dd, last bus=4
PCI: Using configuration type 1 Sep 11 13:24:45 eniac kernel:

ACPI: Unable to load the System Description Tables
PCI: Probing PCI hardware
PCI: ACPI tables contain no PCI IRQ routing entries
[...]

Any suggestion? I think the trouble is dumping/compiling the DSDT
tables. :(

Thank you, Leonardo.
