I tried this (and re-booted) but it doesn't seem to have any effect;
the MTU as given by ifconfig is still 1490:
-----------------------------------------------
[tim at mary tmp]$ cat /etc/sysconfig/network-scripts/ifcfg-eth1
# Lucent Technologies WaveLAN/IEEE
DEVICE=eth1
HWADDR=00:02:2d:21:03:c9
NM_CONTROLLED=yes
MTU=1492

[tim at mary tmp]$ ifconfig eth1
eth1      Link encap:Ethernet  HWaddr 00:02:2D:21:03:C9
...
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
-----------------------------------------------

Nb I solved my problem, as explained elsewhere in this thread.
