I finally got around to trying this, but with no luck. Video output from the kernel still looks "torn". I would have been surprised if nouveau(4) was causing problems at boot time though -- this is the initial output from wscons, not X11. > Searching around, there might be some issues with the specific mac > model nvidia card > e.g. > https://wiki.debian.org/InstallingDebianOn/Apple/MacBookPro/7-1#Black_screen_fix_.28EFI_mode.29 > but myself I can't draw any conclusions out of it, or if it is > affecting NetBSD and your observed issue in any way. I think I remember seeing that before too, but that's with starting X11, not with the initial console video output. On the other hand, who knows? Maybe the PCI-E registers need to be set correctly for wscons to get the video right too? However the boot code only knows one "video mode" (according to "gop"), so, hmmmm.... -- Greg A.
