I *could* set dhcp to request a specific filename - I do this on my home machine by creating a /etc/dhclient.conf file containing "send host-name "my host name";" - but that wouldn't satisfy my curiosity and besides, the host name really should be set by the dhcp server.

I'll try adding DHCP_HOSTNAME to /etc/sysconfig/network-scripts/ifcfg-eth0. Currently it contains BOOTPROTO=dhcp plus a few other things.

/etc/sysconfig/network contains

so the system seems to be ignoring that hostname altogether.
