Matt answered this question for you when you asked it on the 
linuxppc-embedded list last week.  There is no TAH support in 2.4, but 
the IBM EMAC ethernet driver 2.6 does support TAH mode.  You would need 
to backport this driver to use it with 2.4.  Nobody has done this work 
as far as I know, all of the current development effort is focused on 
2.6.  So your options are either to do the work to backport the driver, 
or else use 2.6.
