Just a delayed update on this issue.

I did install the kmod-staging-PAE package from rpmfusion, and also
pulled the RTL8192SU firmware directory from the Realtek web site (was
in a zipped file with drivers and other files)

Once that was done the dongle worked just fine.

I wonder how long it will be before the RTL8192SU driver will be
regarded as stable enough to go into mainstream?  This works without
any problems at all for me.  Or is that a question to ask in the
kernel list?
