Replying to myself again, I'd like to note that replacing the built-in driver
for my NIC with the external driver from the e1000e package on
http://sourceforge.net/projects/e1000/ , as suggested on the redhat.com bug report, fixed the symptoms of the problem (dropped packets) on the desktop machine, and I can now ssh comfortably and use remote gtk+ apps.

Thanks everybody for your help - it proved to be very instrumental in my
investigation and correction. You guys rock!
