NetBSD beastie-1.local 5.0.2 NetBSD 5.0.2 (BEASTIE) #52: Wed Apr 27 08:40:50 EDT 2011  root@beastie-1.local:/usr/src/sys/arch/macppc/compile/BEASTIE macppc

>Description:
machfb is broken for the Mach64GX chip; it does not contain support for it.  I've made a patch which corrects the problem and allows me to boot and use machfb as a console.  How do I submit it?
>How-To-Repeat:
- Use a PowerMacintosh 9500 with the stock Mach64 GX video card (probably any platform with any Mach64 GX/CX should behave the same on any platform).
- Note that machfb does not match the PCI card because the PCI product ID is not in the database.  There is an additional ID mismatch later on once the product ID is added because the ID in the chip itself does not match the PCI product ID for Mach64 GX/CX chips.
>Fix:
I have a patch which fixes it and allows console use, though it looks like some more work is needed; the video output is about a line and a half off, so everything is rotated 1/2 of a screen.  I'll be happy to send two patches, or one once it's fixed.

 Post it to tech-kern for feedback and commentary; with luck, someone
 will commit it. If nobody does, after a few days append it to this PR
 so it won't get lost.

 Mike Macallan on the port-macppc list has indicated that if I get it to =
 him, he'll take care of it (which I'll do after I work out the last =
 tweaks).  Thanks!
