I can confirm this bug using Ubuntu Jaunty Server 64-Bits.
* The card worked fine with Ubuntu-Kernel 2.6.28 using the backport-modules
* The card worked fine with vanilla kernel 2.6.30 and Realtek driver version 1030 *)
* With Kernel version 2.6.31 and 2.6.32 the included drivers show the behaviour from above and the Realtek drivers won't compile with error messages like:
** ieee80211_module.c: 121: error: 'struct net_device' has no member named 'hard_start_xmit'
** r8185_core.c: 4393: error: 'struct net_device' has no member named 'open'
(...)
