The X server doesn't know any 640x870 modes.

Unfortunately, you can't use fbset -x to get a mode definition when you
boot with video=ofonly (unless the fbdev driver at depth 8 is all you
want maybe). The following mode definitions, which I've generated with
the gtf tool that comes with recent XFree86 versions, may help (beware,
my mailer breaks the second line):

  # 640x870 @ 60.00 Hz (GTF) hsync: 54.06 kHz; pclk: 45.84 MHz
  Modeline "640x870_60.00"  45.84  640 680 744 848  870 871 874 901
-HSync +Vsync

  # 640x870 @ 70.00 Hz (GTF) hsync: 63.42 kHz; pclk: 54.79 MHz
  Modeline "640x870_70.00"  54.79  640 680 752 864  870 871 874 906 
-HSync +Vsync
 
  # 640x870 @ 75.00 Hz (GTF) hsync: 68.10 kHz; pclk: 58.84 MHz
  Modeline "640x870_75.00"  58.84  640 680 752 864  870 871 874 908 
-HSync +Vsync
