Apparently the aic7xxx code that pulls the settings out of the seeprom didn't get ported over to the aic79xx driver. Temporarily, to achive what you want, you can just do echo 12.5 > /sys/class/spi_transport/target1\:0\:1/min_period echo 1 > /sys/class/spi_transport/target1\:0\:1/revalidate and that should bring the speed down to U160. I'll see what it will take to get the seeprom functions ported, but they probably won't make 2.6.16.
