I have one of these & got it working with a recent upstream kernel 
(2.6.18-rc4-mm2).  The patch to enable this hardware is included in there, 
and also available here:

<http://www.kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.18-rc4/2.6.18-rc4-mm2/broken-out/gregkh-usb-usb-asix-add-ax88178-support-and-many-other-changes.patch>

I also needed to modify the patch to get things working (per the patch 
below, which I'll send to the maintainer, to see if it's needed as an 
addition or replacement).

When do we expect to resync with the upstream kernel?  If soon, we'll get 
this automatically.

Otherwise, the patch will need to be backported to the kernel rpm (which 
may not be acceptable to the fedora folk).  It applies cleanly but breaks 
during compliation, so some work would be needed there.
