If we can't find the best solution to fix everything, could we just stop
the board from hanging currently?

I looked but was unable to find that information.
There's a strap override in PM_Reg:8Fh on page 169 of the RRG.
And the default of the LPC ROM Address Range registers (page 256)
changes depending on the Lpc_Rom strap, but the value at flashrom run
time says nothing really about the reset value of the register.
