    Er... this patch didn't actually drop that loop (late remark :-).

    I wonder whether ide_register_hw() was much good at all since it didn't 
actually permit to register chips using MMIO: you couldn't pass that info via 
'hw' and it set 'hwif->noprobe' to 0, thus giving you no chance to skip 
probing which wouldn't work anyway; for the same reason it was no good for DMA 
capable chips since you had not time to install ide_dma_check() and other DMA 
methods. Am I right here?

MBR, Sergei
