From when are the sources you used for this ? It should work or at least
it did on the U5 I tried it on at work (that was the 0321 dist).

However there are something else thats not right, I dont get the
transferrates I should on my Netra (which has a ATA66 Acer chip),
however the setup of the Acer chip is OK it seems, but I suspect
interrupt delivery to be extremely slow...
