So it's even worse: the hme uses full duplex mode, while the switch does
use half duplex.

Now there are two things you can try: first, that snapshot is a bit dated now
and a fix for broken nway autonegotiation on some revisions of the hme chipset
might not be in it (I don't remember the exact date it went in). You could
try a newer kernel.

The easiest thing to try is: force full-duplex and then drop back to 
autonegotiation after say 2 seconds. Manually you do this by

ifconfig hme0 media 100baseTX mediaopt full-duplex
(wait a few seconds)
ifconfig hme0 media 100baseTX mediaopt auto

If this works for you, you can automate this via /etc/ifconfig.hme0 (or just
use a newer kernel).
