Ohh, hmm.  Your BIOS has done "odd" things:

        isab0 pnpinfo vendor=0x1166 device=0x0201 subvendor=0x1166 subdevice=0x0201 class=0x060100 at slot=15 function=0 handle=\_SB_.PCI0.IBRG
          isa0
              I/O ports:
                  0x0-0xf
                  0x20-0x21
                  0x40-0x43
                  0x60
                  0x61
                  0x64
                  0x80-0x8f
                  0xa0-0xa1
                  0xc0-0xdf
                  0x4d6

Still, I don't know how the ISA bus is actually allocating resources.  Can
you add some code to the x86 nexus driver to drop into kdb when it receives
a SYS_RES_IOPORT allocation request from "isa0" and get a stack trace from
DDB and reply with the trace?
