Still working on it.
The rev1.18 of acpi_pci_link.c got me confused, but sorted that out.
Following has been done:

 - acpi.c rev1.183 and acpi_pci_link.c rev1.18 boots ok, but loose
   my internal uhub1 and MemoryStick controller. (yes, it's a SONY VAIO ;-)
 - Seems to need "ACPI_OLD_PCI_LINK 1" for acpi_pci_link.c to get
   uhub1 enabled and MemoryStick controller recognized.
 - acpi.c rev1.183 and "ACPI_OLD_PCI_LINK 1" enabled acpi_pci_link.c
   still panics.
 - (1) Removing ACPI_LOCK* stuff seems ok, (2) removing ACPI_DEBUGGER stuff
   seems ok, (3) acpi_Enable()/acpi_Disable() changes seems ok, (4) softc
   changes seems ok, (5) acpiioctl() changes seems ok.

TODO:
 - Check acpi_name() changes.
 - Check acpi_supported_sleep_state_sysctl()/acpi_sleep_state_sysctl() 
   
I'll keep you posted,

Regards,
 Haro
