System: NetBSD milano 1.5V NetBSD 1.5V (GENERIC) #1: Sun May 20 20:43:38 JST 2001 root@nazuha:/usr/src/sys/arch/macppc/compile/GENERIC macppc
Architecture: powerpc
Machine: macppc
>Description:
	  With the  machine:
	PowerMac G4/AGP/350 with included video card
	ATI Technologies Rage Fury MAXX AGP 4x (TMDS) 
	ofb0: 1152 x 870, 8bpp,
	  X Window System use 1280 x 1024 screen, but actual screen 
	is 1152 x 870, resulting VRAM mapping is wrong.

>How-To-Repeat:
	Starting X Window System with minimum setup after installation
	of 20010323 snapshot (1.5S) on this particular machine, 
	gives unorganized screen.
        --------------------------
          (5/6) of screen showing sliced image of X
	  and I could read following text at bottom,
        OSVenderInit
        ukbd_enable: ukbd0: bad call on=1 
	kbd_type = 1
        --------------------------
	I could halt the machine, and it will leave the string
        syncing disks... 2 done

	EXIT called ok
        0 >
        --------------------------
>Fix:
	Not really known, but some work arround is here:

        Before booting NetBSD, at OF level, I can tweak this problem.
        0 > dev screen
        0 > show-modes 
            will tell
        10 1152 x 870 @75Hz CURRENT
        0 > 8 set-mode
            will change to
         8 1280 x 1024 @75Hz
	0 > boot
	Then everything is OK except some portion of the X Window
        screen is out of physical screen and could not read bottom
        part.
