I have a 3CCFE575CT card and similar problems. With kernel 2.6.11 I got around 
4-5MB/s but not more then 600k/s with recent kernels on my old Acer 
TravelMate 513T with a celeron 400.

Using the default interface 'eth0'.
Basic registers of MII PHY #0:  3100 782d 0300 e54b 01e1 45e1 0001 0000.
 The autonegotiated capability is 01e0.
The autonegotiated media type is 100baseTx-FD.
 Basic mode control register 0x3100: Auto-negotiation enabled.
 You have link beat, and everything is working OK.
 Your link partner advertised 45e1: Flow-control 100baseTx-FD 100baseTx 
10baseT-FD 10baseT, w/ 802.3X flow control.
   End of basic transceiver information.

In my case it is using FD.
