I found out that it doesn't seem to be a problem of the specific
chipset, but ahci.ko with that specific HDD.
Doing some searches for my HDD model lead me to that PR:
http://www.freebsd.org/cgi/query-pr.cgi?pr=152817
It describes exactly my problem and I thought that there's also a
solution available:
I took the patch mentioned as "committed to head" in the PR
(http://svn.freebsd.org/viewvc/base/head/sys/cam/ata/ata_xpt.c?r1=215454&r2=217444&pathrev=217444&diff_format=u)
and applied it to RELENG_8_2.
Unfortunately I'm still getting the TFD: 04d1 ahcich Poll error and the
disk isn't seen.

What's my mistake?

Thanks,

-Harry
