work around for busted RS-482 ACPI ? (Long)

[Mike Tancsa]

I like in theory the specs of this board, but I guess the busted ACPI 
is telling me to stay away.  Its an MSI RS482M4-ILD mATX S939 
RS482.  The default boot panics with

CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 4200+ (2193.63-MHz 686-class CPU)
   Origin = "AuthenticAMD"  Id = 0x20fb1  Stepping = 1

   Features2=0x1<SSE3>
   AMD Features=0xe2500800<SYSCALL,NX,MMX+,<b25>,LM,3DNow+,3DNow>
