I think its time for a moderator to step in here. I was assuming you have a pc because you are asking about a pci network card. Unfortunately, it looks like you have a laptop because your lspci output lists pcmcia. Also, you shouldn't have to "add" this module (i'm assuming you mean download). You have a 2.2 + kernel which has this module already.
Now, addressing the specific information you provided.
a. locate (it doesn't look like you inserted your module name after the command; that's why you got no response; so try this one again.
b. modprobe (your kernel module is probably not loading; perhaps you have an irq conflict; typically, NIC cards try to load at IRQ 5 or 10. please provide the output of
cat /proc/interrupts. this will tell us how linux is assigning your irq resources. it may be that you need to check your bios and see if it is trying to load a resource at a conflicting IRQ)
c. ifconfig -a (this is exactly what you should see when you don't have a network card installed and its module properly loaded. when we solve this problem, you will see an additional entry starting eth0)
d. lspci |less (no help here)
e. if you are on a laptop, you need to tell us what kind of PCMCIA card you are using. i don't know why you are asking about a pci network cardl like the SMC1244TX. for a picture of this card see SMC1244TX

if you are on a laptop and you are experiencing an IRQ conflict, you are probably going to have to edit your /etc/pcmcia/network.opts.file to help get this card loaded.
