Hi there. Not sure how much help I'm going to be, since I'm running 2.6.6 (however using memory management, since I have 1GB in this machine). How much memory is in use when you end up loading 
the Alsa drivers? Reason I ask is bc if you only are using about 300MB at the time, there's no real reason that I can think of as to why highmem would be used.
