Download the latest realtek driver (I used rtl8192se_linux_2.6.0019.1207.2010.tar.gz) from the following link:
Install instructions are provided in the fie.
Suspend / resume
Suspend/resume doesn't work out of the box. You need to install a script https://bugzilla.redhat.com/attachment.cgi?id=492164
Put this script in /etc/pm/sleep.d/20_custom-ehci_hcd and make sure it is executable and owned by root.
Suspend to disk still doesn't work: it suspends just fine, but kernel panics on reboot. Suspend to memory is OK.
