It's a 133MHz 486 class system....it's not going to go really much faster 
than what you people are seeing, not the 45xx series.  Maybe if you turned 
on the Linux DMA to DMA drivers (unfiltered bridging type mode) but if 
you're doing anything with the packets heh, you're severely short of being 
able to handle 108mbit on a CISC/x86 system.  Probably 42mbit to 50 
something mbit is all you can expect from these....that said as has been 
mentioned the theoretical limits of these cards are closer to that anyway. 
The Linux driver probably stinks right now, maybe it isnt' setting the card 
up for the 108meg 'turbo' mode.
