No. The problem is amd/early_mtrr and amd/mtrr are wrong. The
amd/early_mtrr does not enable MEM forwarding of A0000-BFFFF to
main memory and amd/mtrr is called to late (it doesn't check if
A0000-BFFFF should be forward to IO or MEM neither).
I fixed it a long time ago. Eric's CPU code just wipe them out.
