+- * This opcode is meant to set NV_PFB_CFG0 (0x100200) appropriately so
+- * that the hardware can correctly calculate how much VRAM it has
+- * (and subsequently report that value in NV_PFB_CSTATUS (0x10020C))

++ * appropriately so that we can correctly calculate how much VRAM it
++ * has (on nv10 and better chipsets the amount of installed VRAM is
++ * subsequently reported in NV_PFB_CSTATUS (0x10020C)).
+ *
+- * The implementation of this opcode in general consists of two parts:
+- * 1) determination of the memory bus width
+- * 2) determination of how many of the card's RAM pads have ICs attached
++ * The implementation of this opcode in general consists of several
++ * parts:
+ *
+- * 1) is done by a cunning combination of writes to offsets 0x1c and
+- * 0x3c in the framebuffer, and seeing whether the written values are
+- * read back correctly. This then affects bits 4-7 of NV_PFB_CFG0
++ * 1) Determination of memory type and density. Only necessary for
++ * really old chipsets, the memory type reported by the strap bits
++ * (0x101000) is assumed to be accurate on nv05 and newer.
+ *
+- * 2) is done by a cunning combination of writes to an offset slightly
+- * less than the maximum memory reported by NV_PFB_CSTATUS, then seeing
+- * if the test pattern can be read back. This then affects bits 12-15 of
+- * NV_PFB_CFG0
++ * 2) Determination of the memory bus width. Usually done by a cunning
++ * combination of writes to offsets 0x1c and 0x3c in the fb, and
++ * seeing whether the written values are read back correctly.
+ *
+- * In this context a "cunning combination" may include multiple reads
+- * and writes to varying locations, often alternating the test pattern
+- * and 0, doubtless to make sure buffers are filled, residual charges
+- * on tracks are removed etc.
++ * Only necessary on nv0x-nv1x and nv34, on the other cards we can
++ * trust the straps.
+ *
+- * Unfortunately, the "cunning combination"s mentioned above, and the
+- * changes to the bits in NV_PFB_CFG0 differ with nearly every bios
+- * trace I have.
++ * 3) Determination of how many of the card's RAM pads have ICs
++ * attached, usually done by a cunning combination of writes to an
++ * offset slightly less than the maximum memory reported by
++ * NV_PFB_CSTATUS, then seeing if the test pattern can be read back.
+ *
+- * Therefore, we cheat and assume the value of NV_PFB_CFG0 with which
+- * we started was correct, and use that instead
++ * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
