I notice that Ollie's flash program (freebios/util/sisflash) already supports that part. If all the writes are enabled etc. you can try just running that program. I have a modified version that will just dump the FLASH part info out if you want that.
In the long term we would really like MTD to just work with this type of thing. I have had no luck getting it to go for these FLASH parts however. ron
