question for AMD chipset support

[Yasushi Okubo <yasushi cabm rutgers edu>]

Hi experts

We had an issue with AMD turion chipset with WS4.0 last December.  It 
did not function properly and needed to install fedora core 4 instead.   
Some people in our group are very interested in AMD's new chip like X2 
or Sempron.  I could not find any compatibility information with AMD 
chips and WS/AS4.0 on the web.  Could you someone give me a direction ?

Thanks,
yasushi
