Very Computer

I tried downloading and installing the Nvidia drivers for FreeBSD the
other day after upgrading my system from 4.6.2 to 4.7.

After following the installation instructions and rebooting I just got
the Nvidia logo instead of xdm, the only command my box would listen
to was ctrl+alt+del.

The machine has a GeForce2 MX400 and the mobo is an Asus A7V133-C
(KT133A chipset)
XFree86 version is 4.2.0

Part of XF86Config:
########
Section "Module"
    Load       "dbe"   # Double buffer extension
    Load       "type1"
    Load       "freetype"
    Load       "extmod"
    Load       "bitmap"
    Load       "glx"
EndSection
...
Section "Device"
    Identifier  "NVIDIA GeForce"
    Driver      "nvidia"
    VendorName  "NVidia"
    BoardName   "GeForce2 MX/MX 400"
    BusID       "PCI:1:0:0"
    Option      "NvAgp" "0"
EndSection
#########
I have also tried commenting out "Load "glx"", that resulted in X
starting but crashing as soon as I tried to run anything and bringing
down the system with it. I added 'BusID "PCI:1:0:0"' after someone
said that it might help solve my problem, it didn't but it didn't
change any error messages so I kept it...

XFree86.log.0 snippet:
#########
(EE) NVIDIA(0): Failed to obtain a shared memory identifier.
#########
I have added SYSVSHM and USER_LDT to my kernel config so that
shouldn't be the problem...

comp.unix.bsd.freebsd is not widely propagated, so you won't
necessarily get much help here.
See http://www.freebsd.org/support.html for better ideas...
<followups redirected accordingly>

Try going to the latest.  [4.2.1, if I remember correctly.]
People seem to be having a little more success with that.
