This is the crucial "bad thing".  This adapter card uses a PCI
interrupt to communicate with the system.  The Linux kernel does not
know how to deduce the interrupt routing for your host bridge, which
appears to be an Acer M1533.  Without that information, the drivers
report "no pci irq", and can't set up interrupt handling correctly.

I've contacted Acer to find out if I can get a datasheet for this host
