[pca] kernel patch 137137-09 : postpatch broken with STMS device names

[Jan Holzhueter]

FYI:
Sun now has a Patch behavior patch :) ( Funny Name I think)
Which should fix the MXPIO Problems:
It's 125555 for Sparc and 125556 for x86.
Problem Description:

6772822 137137-09/137138-09 fails to install bootblk on systems using mpxio

xref file is updated to install this patch before 137137-09 is applied.
