Hi,
I tried to use PM function with the RAIDON ST6600-5S-S2 drives cage,
which has SiI3726 PM chip.
I did never succeed with 2.6.16.16 + libata-tj-2.6.16.16-20060512 patch.
At that point, dmesg output is something like this.
$ dmesg | grep -A 100 libata
libata version 1.30 loaded.

Acutually, the 4 out of 5 drive trays are ocuppied by harddrives.
So, I read docs & patches carefully, added following 2 lines into the
libata-pm.c .
if (vendor == 0x1095 && devid == 0x3726) {
*link_flags |= ATA_LFLAG_HRST_TO_RESUME;
}
After doing this (& re-compile of course), I got it works.
summary of dmesg is ...
