Just a follow-up for the archives...  I loaded the 915resolution port
and configured my rc.conf accordingly:

i915resolution_enable="YES"
i915resolution_modes="3c 4d 5c"
i915resolution_width="1680"
i915resolution_height="1050"

Xorg still failed...

(EE) I810(0): Failed to allocate framebuffer. Is your VideoRAM set too low ??

Fatal server error:
AddScreen/ScreenInit failed for driver 0

However, when I changed the driver in /etc/X11/xorg.conf from i810 to
vesa:

    Identifier  "Card0"
    #Driver      "i810"
    Driver      "vesa"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GM/GMS/940GML Express Integrated Graphics Controller"
    BusID       "PCI:0:2:0"

Now Xorg starts fine.  I'm not sure why it worked but I'm glad it does.
I'll go with the VESA driver unless I get any feedback or more info on
getting i810 driver to work.

Thanks for you help.
