I can confirm that 2.6.15-rc3 works as well:
eth0: 3Com Gigabit LOM (3C940)
      PrefPort:A  RlmtMode:Check Link State
ip_tables: (C) 2000-2002 Netfilter core team
ip_tables: (C) 2000-2002 Netfilter core team
eth0: network connection up using port A
    speed:           100
    autonegotiation: yes
    duplex mode:     full
    flowctrl:        symmetric
    irq moderation:  disabled
    scatter-gather:  enabled

No messages from ping, although the pig is somewhat slower than I would 
expect, ~200us response time.

Looks like a regression, I can't try the latest kernel until Friday, 
it's 260 miles round trip to the machine if it doesn't boot cleanly.
