I saw this message come through at the xfree86 mailing list.  Certainly,
I don't have this problem on xfree86-current.  Some more pull-ups?

You're probably running in 8 bits depth on your card. There's a small
problem with the Xrender extension at 8 bpp on XFree86 4.2.0 that
doesn't leave enough free color cells to display the XFree86 logo in
xdm. If your card has enough memory and bandwith to support 16 or 24
bpp, switch to that . (Add "DefaultDepth 16" or "DefaultDepth 24" to
the "Display" section of  your rXF86Config file). 

If you can't do that, use an icon with less colors in
/etc/X11/xdm/Xresource for the xlogin*logoFileName resource.

This problem is fixed in -current XFree86.
