Sorry about that! I don't know why Gnus split the message when

I've done that as well, and should have said so. The behavior is just
the same. I can load the module and connect to my DHCP server without
any problem, but if I try a large download, the download stalls and I
can find no evidence that any packets are being transmitted or
received.

Agh. I'm sorry again for the confusing information. On this boot, I
had reverted to an earlier kernel, which evidently loaded the r8169
module. (I had moved the module away rather than blacklisted it, just
because that's what the instructions said to do.)

I can't seem to reproduce the unknown header type message today, and
the -x does *not* produce the "ff"s you mention, but I sure do see
some suspicious ffs in the output of dmesg:

That's good to hear, but what about the problems with the USB wireless
card using the rtl8187 driver? And also the PCI wireless card that
produced error messages with the cx23885 TV card driver? Is it
plausible that each of these issues is coincidental? (Given my
evident cluelessness, perhaps so!)

Yes, certainly. I guess I'm misusing terminology. The machine has
Intel Core2 Quad CPU, not an AMD processor, but I thought that the
generic name for a 64 bit architecture was AMD 64. At least, that's
the impression I received from http://releases.ubuntu.com/8.10/.
Again, sorry for the confusion. I'm pretty clueless when it comes to
hardware, architecture and so on.
