We also need to delist some drives from m15w list according to SIMG's 
blacklist. Is there any reason why sata_sil wants irq-pio desparately 
compared to other drivers? Actually it seems that all sata_sil 
controllers seem to be capable of performing PIO using DMA which makes 
PIO support unncessary.
