has anyone done anything with this? it appears to be kindred to the chips
covered by pc/sdmv50xx.c, but with two ports per chip and no bridges.
or maybe there really are bridges and the kw sheet doesn't mention them.
thanks,
tristan

yes, i have a driver. it's pretty amazing that the sata can be driven at ~100mb/s,
given the rather weak cpu. the chip structure is most similar to the kw itself rather
than the kw sata. although its trying to expose only the sata.
unfortunately, it relies on an unreleased version of sd. it's unreleased because
it really didn't go over well. (i'm considering starting over with a port driver/protocol
driver/disk model and ditching sd entirely.)
