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():

FreeBSD 5-CURRENT:
