With the new code, the system did not generate any wrong printf during 
the boot, but the PS/2 mouse could not be used, just like in PR55473. 
After I have applied the following patch, the system really generated 
some wrong printf's, but the mouse worked again. My motherboard is Iwill 
KK266 with Award BIOS.

The patch is here:

--- acpi_pci_link.c.orig    Sun Aug  8 13:12:14 2004
+++ acpi_pci_link.c Sun Aug  8 13:44:34 2004
_at__at_ -467,10 +467,11 _at__at_
    * PCI link status (_STA) is unreliable.  Many systems return
    * erroneous values so we ignore it.
    */
-   if ((sta & (ACPI_STA_PRESENT | ACPI_STA_FUNCTIONAL)) == 0) {
+   if ((sta & ACPI_STA_ENABLED) == 0) {
#ifndef ACPI_OLD_PCI_LINK
       device_printf(pcidev, "acpi PRT ignoring status for %s\n",
           acpi_name(handle));
+       return_ACPI_STATUS (AE_ERROR);
#else
       ACPI_DEBUG_PRINT((ACPI_DB_ERROR,
           "interrupt link is not functional - %s\n",

and the dmesg when the mouse works well is here:
