debian install for KURO-SHEEVA

[東 政一 <azuma-mk@mb.meidensha.co.jp>]

HI!
I bought a KURO-SHEEVA released recently.

It is added  one esata port to the Original SHEEVA-PLUG.
By using SD card 128mb, I  installed the debian squeeze according to 
 http://www.cyrius.com/debian/kirkwood/sheevaplug/install.html

But at the disk detection stage of the installation, a external disk(500gb)

connected via esata port was never detected.
I  think  the esata driver will be included in the base-installer.
Please give me the suggestion for the solution.

BEST REGARDS,
MASAKAZU AZUMA
