Hi

did anyone know if this controller is supported by the sata driver?

i cant see anywhere in sdata.c and sdiahci.c. . . i guess it isnt supported at all, so there is no option to fill some "silly" pci-id somewhere to get it going.

The new 9grid.es server has this controller, it would be a pitty not being able to run plan9 on it and be stuck to the 256M-RAM server :(

(output of lspci -v under the linux the server comes with)
