I've never used that controller, so I may be off a bit.

I suggest you create a /boot partition of about 200MB.
Personally, I have gone to using an IDE->CF adapter and putting /boot on
the Compact Flash. I picked up several adapters for around $5 each a
while back and I use CF cards that are smaller than I feel like using in
my camera (nothing smaller than 4GB in my camera case).
It's not what I know that counts.
It's what I can remember in time to use.
