AMD X2/Opteron Rev E workaround ?

Hi,

it's been a while since this topic was touched, see 
http://lists.freebsd.org/pipermail/freebsd-current/2009-November/013129.html.

I coulnd't find anything more recent than the following commit, which 
prints a warning message, if a suspectible CPU model is detected:

http://svn.freebsd.org/viewvc/base?view=revision&revision=198868



If someone has any patches, even very preliminary ones, I'd be more than 
happy to give them a thorough try on otherwise unused machines.
