Actaully, I made a mistake in the report and this atapci output was from 
2.2.15 (and hdparm output too). Sorry for this stupid mistake.

Here are hdparm and atapci output from 2.4.20-pre5, and additionally 
/proc/ide/piix (quite terse when compared to the output of atapci).

(yes, it segfaults in 2.4 too)

Output of atapci 0.50:
