I find the same results as without the patches. With the parameter set to 'pid', the network connection fails very quickly, but with it set to 'simple' I can ping and ftp files to and from my laptop as much as I like and the connection stays up. In fact, if anything the patches seem to have made the network even more fragile, in that it fails almost instantly once I start some network activity ( < 10 pings). I'm sure this is not the hardware - it works perfectly with Windows XP, with 2.6.23.14 plus the out-of-tree rt61 driver from serialmonkey, with the in-tree driver from 2.6.24.x and with 2.6.25-rc3 with the mac82011's ieee80211_default_rc_algo parameter set to 'simple'. Like I say above, sorry!
