Yep, I had to do that way back then when I got the same sort of setup
working.  Good job figuring that out :)

Just to confirm, this setup works with the current linux-mips.org plus
the above info?  No other patches are required, correct?

I think I'll start an Alchemy/AMD FAQ or something in my directory and
put this information there. Thanks!
