Hmm, I have an Abit KA7-100 (thanks to Trent George!) here with
IBM 75GXP drives on it (btw the KA7-100 is a VERY nice board)
so I will give it a shot on bonnie and world later today to give
you some numbers. I would go for the ATA setup and extra RAM
but I'm biased :)

PS I have ATA100 support for the HPT370 used on the KA7-100
running, but I haven't gotten to the Promise Ultra100 lying
here next to me yet, watch -current for updates on it...
