I built a 2.6.28.1-9 kernel to get the minstrel code for ath5k.  The 
kernel for Suse 11.1 is 2.6.27.7-9.  But that means that more could have 
changed besides the rate control code.

It looks like minstrel and pid give about the same result, a bit worse that 
the ath_pci driver right now.  Performance seems to vary from day to day.  
I'll experiment some more, and switch transmission channels.  I'm not getting 
the really poor performance with ath5k right now.

I haven't looked yet - is there a way to switch to 'pid' rate control without 
rebuilding the kernel?
