I now have the rtl8187 driver working on the built on board NIC rtl8187 in fedora 7.
Apparently hey put a rtl8187 driver in the kernel and i have gooten to work but it is not very clean.
Here is the way i have gotten it to work.
edit the modprobe.conf file and add the line
alias wlan0 rtl8187
configure wlan0 in system-config-network but do not activate
in a root terminal use iwlist scan to see if device wlan0 is present
use ifup wlan0 (it will probably give errors like set bit rate not supported)
use control c if hung on the dhcp
do another ifup wlan0 and the network should come up
well it did for me anyway
no hangs after it comes up
did hang before i got it to come up if if you try to activate with system-config-network
if anyone has a better way please let me know
