This is the tg3 patch i used for the testing - against whats in Daves
net-2.6.24 tree. Patch may be a bit hard to read.
For an example of an LLTX version look at the e1000 in the older git
tree at:
git://git.kernel.org/pub/scm/linux/kernel/git/hadi/batch-lin26.git

If the intel folks will accept the patch i'd really like to kill 
the e1000 LLTX interface.
The tg3 in that tree used the old style batch_xmit() interface.

cheers,
jamal
