I have seen similar problems with a P133 system  (Intel  Endeavor  MB)
and a Diamond Stealth Video VRAM 64 (a.k.a 3400) adapter.
Probable cause was that base of frame buffer  memory  was  not  mapped
correctly (adapter hardware/firmware bug ? MB BIOS bug ?  human  error
on  my  part  ? ;-). I  have  found  the  following (admittedly dirty)
workaround in the XF86Config file:

Section "Device"
    Identifier  "Diamond Stealth 64 Video VRAM"
    VendorName  "Diamond"
    BoardName   "Stealth 64 Video VRAM"
    MemBase     0x8000000
    Option "sw_cursor"
    Option "Diamond"
# Use Option "nolinear" if the server doesn't start up correctly
# (this avoids the linear framebuffer probe). If that fails try
# option "nomemaccess".
# Refer to /usr/X11R6/lib/doc/README.S3, and the XF86_S3 man page.

    I've RTFMed. It says: "Refer to your system administrator"
            But... I *am* the system administrator :-]
