Is that true even for the older stuff such as a PDC20265?
It appears that FreeBSD 4-STABLE blacklists some older (before-TX2) Promise chips because they apparently lock up when used with tagged command queueing. I haven't yet looked at the ATAng driver merged into FreeBSD 5-CURRENT.
FreeBSD 4-STABLE blacklist code in function ad_tagsupported(): http://www.freebsd.org/cgi/cvsweb.cgi/src/sys/dev/ata/ata-disk.c?rev=1.60.2.24&content-type=text/x-cvsweb-markup&only_with_tag=RELENG_4
