    Actually, I've considered removing TRM290 hacks from that function and 
re-implemeting the whole thing in the driver but that wouldn't sever this 
driver's ties with CONFIG_BLK_DEV_IDEDMA_SFF since the latter gets selected by 
CONFIG_BLK_DEV_IDEDMA_PCI...

    I'd keep all the initilaized variables together...
