Fatal IO Error 22 on start

["Christopher Penney" <penney at msu dot edu>]

I just installed cygwin and am having trouble getting X to run.  I'm using a
Dell Inspiron 8600 (Pentium M 1.6GHz, 1680x1050 LCD, ATI Mobility Radeon
9600 Pro) and I'm running WinXP Home (fully patched).  When I start I get:

$ export DISPLAY=127.0.0.1:0.0
$ startx

XIO: fatal IO error 22 (Invalid arguement) on X server ":0.0"
after 0 requests [blah]

My XWin.log file says:
