Look,

it's no use speculating about a linux problem here unless you fix your 
hardware to generate the necessary interrupts. The IDE driver will not work 
without. The probing of the card (IDE IDENTIFY command) will succeed anyway 
since it's done polling. But after that you explicitely need interrupts.
