Odds are there is another driver in your system then that is attaching 
to the tdm400 before the wctdm driver.  I've seen where the hisax driver 
attaches first.  Does 'lsmod | grep hisax' show that hisax is loaded?

You can see what drivers may be configured for a board by looking at the 
/lib/modules/`uname -r`/modules.pcimap file.  The tdm400 uses a vendorid 
of 0xe159 and a device id 0x0001.  Search for any driver in the pcimap 
file that indicates support for that driver, and add it to the 
/etc/modprobe.d/blacklist file.

Something like:

blacklist hisax
blacklist hisax_fcpcipnp
