Subject[PATCH] gamecon.c and PSX DDR controllers
PSX DDR controllers don't work with gamecon.c. I sent a quick fix for
the crash-on-load to Vojtech a while ago, but didn't have time to
really fix it until now, and it didn't actually make DDR controllers
*work* (just load without an oops) so I can't blame him for ignoring
it. :-)

It turns out that getting DDR controllers to function with gamecon is
very simple -- we just forgot to check for them when looking in
status_bit. Here's the three-line patch. Could someone get this into
2.6.10? Thanks a lot.
