I can hardly belive that you get only 2 devices with the eata driver
while you get all with the eata_dma, unless some boundary condition
is different. Are you compiling eata and eata_dma each one by
itself into the kernel? If you load them as modules you face
the SD_EXTRA_DEVS limit of 2. Moreover the wide devices should be
all close to the board (which must be high and low terminated)
and only the last wide device must be high terminated, then
in the scsi chain there should be all the narrow devices with the last one
(low) terminated.
The only way to control  the board speed is using either dptmgr
or the onboard bios at powerup, the driver has no control at all
on this feature.
