I just wanted to say that finally with ACPI version 3.00 my Gateway 7405GX laptop is fully functional - including USB ports and most importantly the Broadcom WiFi. What I had to do was add /EIS /AFS (W4 kernal) switches and explicitly describe every IRQ link in ACPI.CFG making sure not to link any to IRQ10 (used by ACPI itself) AND keep them to IRQ 9 and above.
The only problem left is with APM... all functions work, except after a suspend, hitting the power button to return turns off the computer. I tried the /VBE switch, but it causes the computer to lock up when hitting the power button to return. Maybe there is a switch I overlooked... I'll keep trying.
Thanks for your continued great work on ACPI.
