I don't know about the reset. i think that the K8 does have the same
issue but the amount of code copied is much less. The fam10 code is
much larger.

The thread you want to look at is this one:

I think that a better solution is to fix up the disable car and copy
code to cache the rom.  For example adding

set_var_mtrr(1, XIP_ROM_BASE, XIP_ROM_SIZE, MTRR_TYPE_WRBACK);

to set_init_ram_access() would address the issue. Maybe you can try that.
