the switches can handle 1000BaseT flawlessly but for some reason I still 
don't know I cannot change the link speed on the server...

It won't work from the command line:

# ethtool -s eth0 speed 1000 duplex full autoneg off
Cannot set new settings: Invalid argument
  not setting speed
  not setting duplex
  not setting autoneg

nor from the configuration files for eth0 under 
/etc/sysconfig/network-scripts/ifcfg-eth0 (in that case, I'd need to add
ETHTOOL_OPTS="speed 1000 duplex full autoneg off" in there)

therefore the switch negotiates 100BaseT...which could be the reason 
for my problems... :-/
