It looks like that's the right module to use.  Does dmesg say anything useful from the e1000e driver?

Perhaps the 10.04 driver is older than the card, so you could get a newer version (and instructions 
for using it with your kernel?) at http://sourceforge.net/projects/e1000/files/

With wireless cards this sort of symptom is usually because the driver doesn't have the firmware it 
needs.  I don't see anything that says your card needs firmware (assuming it's the 82577L{M,C} that 
thinkwiki says it is).
