Thats long been broken. Should be correct in the libata driver
I've looked thru the specs and it seemed to me that ULi hardware is much broken PIO wise: their max active time is 8 cycles even on taskfile access which gives 240 ns while standard requeires 290 ns for modes 0 thru 2...
I've also noted that the tuneproc() method in both cmd64x.c and alim15x3.c seems to misdo recovery calculation, taking address setup into account -- that should be slightly overclocking PIO modes 0/1 (ULi docs don't shed much light on how it should be calculated)... Well, this seems fixed in libata drivers.
