I will apply the patch and test it as you have requested.

To be clear, the output of the hpdarm -Istdout /dev/hde command that I reported
a few minutes ago was performed with a vanilla 2.6.23.12 kernel that, as
you pointed out, was utilizing the it821x driver rather than the
pata_it821x driver.  That may be obvious to you, but I thought I should
be explicit about it.

Now, with reference to the 2.6.23.12 kernel with the unpatched version of the libata code, I don't
think I can do much with hdparm since the raid array does not seem to be
recognized as a device.  If my understanding is correct based on the
kernel boot messages, it seems to me that pata_it821x is going to treat
the array as a scsi block device, which on my system will configure as
/dev/sdb if the array is recognized.
