HOW-TO by myself:
-configure your kernel settings:

# PCCARD (PCMCIA/CardBus) support
#
CONFIG_PCCARD=y
# CONFIG_PCMCIA_DEBUG is not set
CONFIG_PCMCIA=y
CONFIG_CARDBUS=y

#
# PC-card bridges
#
CONFIG_YENTA=y
# CONFIG_PD6729 is not set
# CONFIG_I82092 is not set
# CONFIG_TCIC is not set
CONFIG_PCCARD_NONSTATIC=y

#
# Wireless LAN (non-hamradio)
#
CONFIG_NET_RADIO=y

-save your kernel setting and compile it as always
-reboot your system
-download ndiswrapper-source from sourceforge.net
-download dwl-g650+ driver from the d-link ftp-server
-install the wireless-tools
-unpack and install the ndiswrapper as follows:
*cd ndiswrapper/
*make distclean
*make
*make install
-unpack the dlink driver to the root homedirectory
-load the driver with ndiswrapper:

ndiswrapper -i /path/to/*.inf

-check the status of the dlink driver:

-load the module ndiswrapper:
