> I've increased the delay to "11000, 15000, 20000 and 40000" (like you can see in the patch) and nothing happens. In addition, I've changed the disk from cmdide to viaide (channel 1 drive 0), nothing. 

Hum, so it looks like this drive will never assert DRDY by itself.

> I've attached the patch and dmesg.boot with "wdcdebug_mask" to "0x10". For more info I've just booted an OpenBSD-3.4-current and the disk is detected without problems. Sorry I don't know how I could help. :\

It can.
It seems openbsd issue a dummy command before waiting for DRDY.
Can you try the attached patch ?
