Kernel modules (for example, your rtl8180_rh73.o) and the kernel need to be compiled with the same major version of gcc. Someone compiled the module with gcc 2, and your kernel was compiled with gcc 3.
Downgrading your gcc version could be a major undertaking.
I would try to find the module compiled with gcc 3, or compile it yourself.
Is the card a Realtek 8180? If so, this site
