Yes, I've only seen sk0 configured properly once (maybe 
twice)--dhcpcd normally times out waiting for carrier when attempting 
to configure it.

No, it's not.  By the way, the two DHCP servers are a failover pair 
running ISC's DHCP server version 4.2.5, but that's irrelevant to 
DHCP clients to the best of my knowledge.

I commented out "require dhcp_server_identifier" in /etc/dhcpcd.conf 
but it made no obvious difference.

Using dhcpcd's  --nohook mtu  option didn't help:

# dhcpcd --nohook mtu fxp0

So the -U option gave no output, even when I used it on the PC whose 
fxp0 NIC works (after configuring the NIC via sysinst's menu).
