Cannot get wireless atheros card to be recognized in pfSense 2.0.1

[chriv]

I read some similar threads, including this one: http://forum.pfsense.org/index.php?topic=12807.0, but I didn't find any answers.

Simple problem: pfSense 2.0.1 doesn't load the driver for my atheros wireless card in my Acer netbook.

Here's some applicable output:

#: dmesg | grep -i ath
ath0: <atheros 2424="" 5424=""> irq 17 at device 0.0 on pci3
ath0: 0x10000 bytes of rid 0x10 res 3 failed (0, 0xffffffff).
ath0: cannot map register space
device_attach: ath0 attach returned 6</atheros>

#: pciconf -lv
...
ath0@pci0:3:0:0:        class=0x020000 card=0xe00d105b chip=0x001c168c rev=0x01 hdr=0x00
    class      = network
    subclass   = ethernet

Anybody have any ideas?  I haven't the foggiest clue how to recompile the kernel without the atheros driver to slip in the atheros kernel module, so that won't work for me without some pretty explicit instructions.  I don't think it would fix these errors anyway.

Wrong diagnosis. The driver is already built in the kernel and it is effectively reporting the I/O subsystem is not correctly setup for the card.

#: dmesg | grep -i ath
ath0: <atheros 2424="" 5424=""> irq 17 at device 0.0 on pci3
ath0: 0x10000 bytes of rid 0x10 res 3 failed (0, 0xffffffff).
ath0: cannot map register space
device_attach: ath0 attach returned 6</atheros>

After a quick look through the FreeBSD source code I suspect this means something like:
1. There isn't enough kernel address space or page table entries to map the 0x10000 (64k) bytes of PCI memory address space on the ath device into kernel memory space; or
2. An upstream PCI bridge doesn't have enough memory address space to allow access to all its downstream devices AND this device;

Is this card a mini PCI-Express card replacing the netbook's standard WiFi card?

Is pfSense running in some kind of virtual environment?

Was the card in the system at boot time?

Have you tried a snapshot build of pfSense 2.1?
