Well, I put a 2432 into my box and recompiled with target mode enabled.  
Nothing fancy.

:)

A 23XX card in it's place works just fine. 

I believe, due to the architecture difference between the 4G/8G and 2G 
cards that it just doesn't work right now.
The 4G/8G architecture does nothing in target mode except DMA the 
incoming data.  the 2G cards do some things
for the driver.

I was hoping that someone has some patches in their trees just lying 
around that I could look over and test for
4G target mode support.  :)
