Um, I recently made a change to the script that expands the build ID from a 32-byte hex 

[3] tag="BLID" length=20
  00000000  b5 9b b5 6c 76 7e 1e 34 ef 86 45 c6 73 31 f6 a6  |...lv~.4..E.s1..|
  00000010  5b 8a 5c 3e                                      |[.\>|

to a 64-byte string:

[7] tag="BLID" length=40
  00000000  39 65 37 64 39 35 66 35 32 62 63 30 36 66 37 63  |9e7d95f52bc06f7c|
  00000010  66 31 61 34 36 37 37 35 61 64 34 35 30 63 63 63  |f1a46775ad450ccc|
  00000020  65 66 66 34 35 35 65 34                          |eff455e4|

I'm assuming you want me to change that back?  I didn't realize the build ID was actually going
to be used by the driver.
