I don't have much experience with having two ethernet cards in a machine, so I don't know how much that would affect this situation. I do know that with my SMC 100/10 switch card I did loose a lot of packets when running from a 10 mb hub. I moved it over to a 100 mb hub and it runs awesome. My ifconfig also says 10mb because the tulip driver first probes 10mb. However, after boot up, once I start sending packets it says "Enabling 100TX port" despite the fact it says 10mb on ifconfig. Also, my download capabilities have shown it. ( On our internal network I can download up to 1.3 MB/sec =), my scsi hard drive griding as fast as possible the whole time and being on a T3 backbone I'm usually bottle-necked by others ) If you load the driver as a module you can force it to probe other ports first... in your case the 100TX. At http://cesdis.gsfc.nasa.gov/linux/drivers/tulip.html you will find more information on this, including the options you can send to the module. They also have mailing list for problems with the tulip driver.
