Thanks to Eric "Shubes of Phoenix Linux User Group who corrected my 
XF86Config, TwinView works (mostly) on my HP laptop under 9.1.  The only 
inconvience is needing to comment/uncomment a few lines depending upon 
whither the external monitor is present or not.  When configured for an 
external monitor, TwinView insists on using the external as the prime 
monitor, hence no system icons available if no external.

The following is the "Device" section of XF86Config for having an external 
monitor (but with non-dual statements commented):

Section "Device"
   BoardName    "0x031a"
   BusID        "1:0:0"
   Driver       "nvidia"
   Identifier   "Device[0]"
   VendorName   "NVidia"
   Option       "TwinView"    "True"
#  Option       "ConnectedMonitor" "DFP, CRT"
   Option       "TwinViewOrientation" "CRT-0 RightOf DFP-0"
   Option       "MetaModes"  "1024x768, 1024x768; 800x640, 800x640; 
640x480, 640x480"
#  Option       "MetaModes" "NULL, 1024x768; NULL, 800x640; NULL, 640x480"
   Option       "HorizSync"   "CRT-0: 31-64, DFP-0: 31-64"
   Option       "VertRefresh" "CRT-0: 50, DFP-0: 60"
#  Option       "HorizSync"   "DFP-0: 31-64"
#  Option       "VertRefresh" "DFP-0: 50-78"
   Option       "SecondMonitorHorizSync"   "CRT-0: 31-64"
   Option       "SecondMonitorVertRefresh" "CRT-0: 50-78"
EndSection

The following is the "Device" section for not having an external monitor, 
but saving the dual statements as comments.

Section "Device"
   BoardName    "0x031a"
   BusID        "1:0:0"
   Driver       "nvidia"
   Identifier   "Device[0]"
   VendorName   "NVidia"
   Option       "TwinView"    "True"
#  Option       "ConnectedMonitor" "DFP, CRT"
   Option       "TwinViewOrientation" "CRT-0 RightOf DFP-0"
#  Option       "MetaModes"  "1024x768, 1024x768; 800x640, 800x640; 
640x480, 640x480"
   Option       "MetaModes" "NULL, 1024x768; NULL, 800x640; NULL, 640x480"
#  Option       "HorizSync"   "CRT-0: 31-64, DFP-0: 31-64"
#  Option       "VertRefresh" "CRT-0: 50, DFP-0: 60"
   Option       "HorizSync"   "DFP-0: 31-64"
   Option       "VertRefresh" "DFP-0: 50-78"
   Option       "SecondMonitorHorizSync"   "CRT-0: 31-64"
   Option       "SecondMonitorVertRefresh" "CRT-0: 50-78"
EndSection

Hope this helps anyone else trying to do the same thing.
