Howdy all,
Sorry for the cross post, but in retrospect, I thought [EMAIL PROTECTED]
was a better place to ask this question than [EMAIL PROTECTED]
There has been some discussion about the desire for nVidia drivers for
the PPC architecture on both this list as well as on [EMAIL PROTECTED]
(it seems to be a big pain point for 12"/17" PowerBook owners who want
to run XFree86), but I haven't seen anything along these lines. This
idea was originally posted here:
http://www.nvnews.net/vbulletin/showthread.php?s=&threadid=25418&highlight=linux+ppc
I'm reposting it here to see if I can't generate some discussion. By the
way, if someone thinks this would be more appropriate to post to
[EMAIL PROTECTED], please let me know, and I will forward it on. Here's
the (mostly) original text:

So far, I haven't had any response via the nV News site (though the post
is relatively young). Any thoughts? Am I insane for proposing this? I
will admit I know absolutely nothing about graphics hardware or driver
development.
I apologize in advance if this has been discussed before (and I wasn't
paying attention). Anyway, thoughts, comments, etc. are welcome and
encouraged.
