The Athlon claims to support FXSAVE, so I dont think that explains it. There
is a problem with the older RH kernel (2.2.14 one) which sees the PSN flag
is set and tries to disable PSN but the AMD chips use the flag for a
different purpose

It sounds like Redhat patched the kernel to support the Pentium III XMM
extensions and the kernel is misdetecting the Athlon as a PIII.

  When we upgraded the motherboard, we got consistant GPFs right after
  the line:
  Enabling extended fast FPU save
 
 It sounds like Redhat patched the kernel to support the Pentium III XMM
 extensions and the kernel is misdetecting the Athlon as a PIII.

The Athlon claims to support FXSAVE, so I dont think that explains it. There
is a problem with the older RH kernel (2.2.14 one) which sees the PSN flag
is set and tries to disable PSN but the AMD chips use the flag for a
