BTW, interesting. In your VBIOS, it tells us to do

0xcbf2: 7a 80 00 10 00 00 00 00 e0 ZM_REG R[0x100080] = 0xe0000000

Which is why that bit gets lost on resume (but not on kexec, since init scripts don't run, since the adapter is already init'd). Good to know, that means that any fixup would have to be made _after_ the bios gets executed... or more likely, as part of the COMPUTE_MEM thing (meminit in core/subdev/devinit/nv20.c), which gets executed in "init script 5", which happens after that "init script 1" which contains the 0x100080 = 0xe0000000 command. Although then it wouldn't happen on boot, so nevermind. Has to happen after the vbios executes.
