Yes, I scanned eBay almost 2 years for it and 3 or 4 month ago it came up and is working very well. I have X running on it and have the same problems with the keyboard like you do.
Anyhow I will try to port the NetBSD CV64 driver to Amix, even I'm not a unix driver expert. This time I study some old Unix SR4 programmer books that will hopefully help :-)
If this will ever work we can talk about the tiga card ;-)
