Xorg can't find my graphics card

I didn't know that trick! Here are the results for the curious:
# pciconf -lv | grep -B 4 VGA
vgapci0 at pci0:0:16:0:    class=0x030000 card=0xa5b80208 chip=0x011010de
rev=0xa1 hdr=0x00
    vendor     = 'Nvidia Corp'
    device     = 'NV11 GeForce2 MX / MX 400'
    class      = display
    subclass   = VGA

I did search the archives, but not hard enough I guess.

# sysctl hw.ofwfb.relax_mmap=1
hw.ofwfb.relax_mmap: 0 -> 1

This did fix my installation, I can't believe it!

I returned to the FreeBSD documentation and completed the steps, resulting
in a final /usr/local/etc/xorg.conf. I did find out that you cannot have
ANY xorg.conf file (regardless of actual name) in /etc or /usr/local/etc
when you first run #X -configure

I also learned that if #startx doesn't run, you should troubleshoot that
before running #X or #xorgconfig.

I may have more questions, but for now I'm giddy! Thanks for the friendly
help!
