[ut2004] 2.6.6 kernel configuration

[Gian Paolo Mureddu]

No, that didn't work either. If I disable at all my NAT configuration in 
my router, I can get to the join game menu (completely idle of course), 
but I even do enable NAT and MASQ the freaking game crashes! This has 
somethig to do with my kernel, I'm sure, since I had no problems with 
the other one (and I did not change any of the router's configuration) 
What in this world could that be!!
