Ok it really works ;)
But there's another problem in 2.5.8 with ide patches until 37 applied (they don't appear with 2.5.8 and ide patches until 35), the unexpected interrupts (look at the relevant dmesg output at the bottom). They appear with and without TCQ enabled.
If you need more informations, just ask :)
