My experience was that when I had a ATA100 device on ATA0 master and a PIO4 CDRW device on ATA0 slave the best the system could do was ATA33. moving the cdrw to ATA1 master allowed the ATA0 master ATA100 device to be recognised as ATA100. This is with the 80wire ATA100 data cable. So yes, I'd say its at least seeing there is something there, as its reduced the UDMA66 to UDMA33 on ata0.
