I use a vanilla kernel 2.4.20 with the ACPI patch 20021205. Did you use 
another ACPI patch? Perhaps this part has changed...

The last part of the patch is for the function acpi_os_table_override:

<<original>>

acpi_status
acpi_os_table_override (acpi_table_header *existing_table, 
acpi_table_header **new_table)
{
         if (!existing_table || !new_table)
                 return AE_BAD_PARAMETER;

         *new_table = NULL;
         return AE_OK;
}

<<patched>>

acpi_status
acpi_os_table_override (acpi_table_header *existing_table, 
acpi_table_header **new_table)
{
         if (!existing_table || !new_table)
                 return AE_BAD_PARAMETER;

         *new_table = NULL;
         if (strncmp(existing_table->signature, "DSDT", 4) == 0)
                 *new_table = (acpi_table_header*)AmlCode;
         else
                 *new_table = NULL;
         return AE_OK;
}

I hope this will help. Please tell me whether you had success ;-)

Regards
Heiko
