What's suspectfor me is why the fc909 is still listed on the Kconfig as supported controller. I request this lsi909 card 8 mnoth ago. This was a new card and the seller told me that this card was often sold and he had also a lot of this cards allways in his stock. (maybe i' m the first user of this card which shuold run with linux ;-) .. You wrote any changes which must be done to support this card with the current kernel. Is this a lot of work for you?
