Stefan,

Any particular reason you use the -s option to cygpath?  The following
should work (quoting adjusted as well):

APPDATA="`regtool get '\HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\Shell Folders\AppData'`"
HOME="`cygpath -u "$APPDATA"`"

Also be aware that bash doesn't read /etc/profile unless it's a login
shell (i.e., has the --login option).  You can also pass the "-ls" option
to the xterm for that effect.
