* to be 0 (they're high bits of fields that never got big values)
* - NV10+ little-endian card: bit 7 is guaranteed to be 1 (MSB of
* stepping, which is always 0xaX or 0xbX), bit 31 is guaranteed
* to be 0
* - NV10+ big-endian card: like above, but with byteswapping - bit 7
* is 0, bit 31 is 1
* - something is broken with BAR0 access and ID returns 0xffffffff
* - both bit 7 and bit 31 are set
