1844 * (and subsequently report that value in 0x10020C)

1850 * 1) is done by a cunning combination of writes to offsets 0x1c and
1851 * 0x3c in the framebuffer, and seeing whether the written values are
1852 * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
1854 * 2) is done by a cunning combination of writes to an offset slightly
1855 * less than the maximum memory reported by 0x10020C, then seeing if
1856 * the test pattern can be read back. This then affects bits 12-15 of
