wi0: No Mem space on prism2.5?

[Rahul Siddharthan <rsidd@xxxxxxxxx>]

Not a new problem, but I remembered it now that I'm in a wifi-zone and
it's biting me... (though I still have wired ethernet)

My wireless card is not configured during boot: it says
wi0: <Intersil Prism2.5> at device 9.0 on pci0
wi0: No Mem space on prism2.5?
device_probe_and_attach: wi0 attach returned 6

The identification is correct, I think.  FreeBSD 5 used to configure
it.  Linux dmesg says

Detected Orinoco/Prism2 PCI device at 00:09.0, mem:0xD000A000 to
0xD000AFFF -> 0xdcb2d000, irq:10
. ...
eth1: Looks like an Intersil firmware version 1.4.9
eth1: Ad-hoc demo mode supported
eth1: IEEE standard IBSS ad-hoc mode supported
eth1: WEP supported, 104-bit key
eth1: Station name "Prism  I"
eth1: ready

DFly failure is with or without acpi.  Kernel is up-to-date

Ideas?

Thanks
