OK, first things first. txqueuelen sets the size of the transmit queue,
not the speed of the interface. Hardcoding the speed of the interface is
a bit tricky. If you are using modules for the NIC drivers, some drivers
take an option which sets speed of the interface. Is there a speed status
light on the NICs? If so, what does that say? It still sounds like a
speed mismatch; have you tried rebooting or restarting networking after
connecting to the dual-speed hubs? That would force negotiation.
