I'm actually not entirely sure why the W25Q80 and W25Q32 were marked as "OK" for erase but not write. In any case, I've successfully read/erased/written all three of these Winbond chips using nm10 and amd870 based mainboards.

I see no reason why the W25Q16 would not work as well, but I don't have one to try so I left it out of this patch.
