This patch works - system boots fine. Only issue seen was 'suspend request 
ignored - not ready yet' yesterday, but not (yet) today, when pressing on/off 
button (maybe designed as suspend/resume button). I would like to put this 
patch on my page, too - any objection?

On the other side, from the VT82C686B datasheet it looks like I need a driver 
for this system resource, which should be PCI function 4 - output from 
pciconf -lv related to this is

isab1 at pci0:7:4: class=0x060100 card=0x00b50e11 chip=0x30571106 rev=0x40 
    vendor   = 'VIA Technologies Inc'
    device   = 'VT82C686A/B ACPI Power Management Controller'
    class    = bridge
    subclass = PCI-ISA

Any idea on this, apart from writing new driver?
How could I find info on this device from asl? I do not understand this,
