It looks like there's a problem with the rom for the dGPU:

1047552M of vram is obviously wrong. How much vram is supposed to be
on the card?

Throwing in some writel and readl tests before even trying the dma
test,
I see that the memory isn't being changed with writel in the first
place.
----
tmp = 0xDEADBEEF;
writel(tmp, ptr);
tmp = readl(ptr);
if (tmp != 0xDEADBEEF)
DRM_ERROR("radeon: ring %d memory write failed (0x%
08X)\n", ring->idx, tmp);
----
radeon: ring 3 memory write failed (0xDFCFFBFF)
Looks to me like we're trying to write to a rom address, but I'm a
complete novice at this so I could be completely off.
I'm using kernel 3.13.0-0.rc1.git3
What else could I look at?
No, that patch does not completely solve the problem. The memsize is
right, now, but the dma test still fails the same way.

Something still seems problematic with the rom. Does this help?

You might also try 64 rather than 128 if 128 doesn't work.

Those had no effect.
I hacked the dsdt to fix the ATRM error. I don't know if this is
something that can be worked around or if I'll have to have MSI fix
their bios, but if it can, here's a successful init once the bios can be
read:
How did you fix the dsdt? What did you have to change?

In the following I tried changing VROM to 512000 like every other
version I could find, but it still overflowed, so I changed the TVGA
buffer to 0x10000 (big enough to hold 524288) which cleared that error.
I'm still confused how we're getting to that code path since Arg0 is
0xf000 and Arg1 is 0x1000 which should add up to 0x10000, which is not
<= 32. Everything I've read suggests that integers should be 64 bit but
it seems to be being compared as a 16 bit word.
