3.2.18-pclos2.bfs
Going from the driver you tried to build, the last kernel I can find that used it is the 2.6.31.9-pclos3 kernel, from the old 2007-2009 PClinuxOS release. That's pretty old and outdated, and probably why it wouldn't build with the 3.2.18 kernel.
In that old kernel, the r8180* files are found in the kernel sources at

They don't show up in any of the later kernels.
Using the same relative path with the kernel you are using I found this in the Kconfig file.
config R8187SE
tristate "RealTek RTL8187SE Wireless LAN NIC driver"
depends on PCI && WLAN
depends on m
select WIRELESS_EXT
select WEXT_PRIV
select EEPROM_93CX6
select CRYPTO
default N

If built as a module, it will be called
r8187se.ko.Which is why I had you load that module, to see if it would hook up with your device.
The Makefile only references four of the r8180* files;

The Realtek site page, from the AZIO provided link only shows support for 2.6.x kernels, with the last update time listed as 2010/1/25, for the RTL8185L, and 2010/10/6, for the RTL8187L, which could mean that they don't have kernel 3.x.x support yet.
Were it me, I'd be talking directly with LinPC, or AZIO, or both, to find out what the status of this card is, at present, relative to drivers for 3.x.x kernels. It could be the card has gone obsolete, and LinPC is unaware of that.
