Do you use the 2.6.18 kernel? (If you are not sure, look at the output
that you get when you run "uname -a" in a terminal.)

Open a konsole window (or any other X terminal) and paste this command
into it:

lspci -knn | perl -n0e 'split/(?<=\n)(?=[0-9])/;foreach(@_){if(/Ether/){print$_}}'

Hit ENTER and post the output here. If you have trouble with this long
command, just use the first part ("lspci -knn") and cut out the relevant
part of the output yourself. (The lspci command list all your PCI
devices; we only need the lines related to network cards.)

AFAIK, this device is handled by the b44 driver. As a first diagnostic
tool, I would run

dmesg | grep b44

right after boot. Does that turn up anything?

Maybe you just need a newer kernel.
