[PATCH] sis190: resurrection

Raise the sis190 driver from the dead

The driver handles the integrated network device found on SiS 965L
chipset. It follows the classical (non-napi) interrupt-driven model
and provides minimal ethtool support.

The code comes from a heavy cleanup/rewrite of the original code
which was removed from the kernel on 14/04/2004. Since the r8169
driver does not work too bad and there will probably be (at least)
a few months of improvements/testing/fixing, I made the code as
close as possible to the r8169 one.

Pascal Chapperon <pascal.chapperon@wanadoo.fr> deserves some special
credit for testing and bug-catching. Many thanks to Lars Vahlenberg
as well.
