The wd33c93 is what we already support. As long as the harddisk are attached to it, it should work. The wd33c95 is a rather strange chip, and from the datasheet I have here, it looks like a lot of work to write a driver for it, because besides the kernel code, you have to write sequence code for the chip, too. > The install kernel you're using (and oh god, is it ever a bad one) > is broken in that serial console won't work. Yes, I should have looked > into it way back when. When I did the new console code, I first made the serial console working. As far as I remember I had to do some ugly hacks, but I'll try to clean it up and check it in.
