-	 * subsequently reported in NV_PFB_CSTATUS (0x10020C)).
-	 *
-	 * The implementation of this opcode in general consists of several

-	 *
-	 * 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) 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.
-	 *
-	 *    Only necessary on nv0x-nv1x and nv34, on the other cards we can
-	 *    trust the straps.
-	 *
-	 * 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.
-	 *
-	 * This appears to be a NOP on IGPs and NV4x or newer chipsets, both io
-	 * logs of the VBIOS and kmmio traces of the binary driver POSTing the
-	 * card show nothing being done for this opcode. Why is it still listed
-	 * in the table?!
