Hmm... as commit message r6211 says: I just used Intels newest version (v.22) of
the x86 processor manuals, available at
 http://www.intel.com/products/processor/manuals/index.htm
In Volume 2a, there is the documentation for the CPUID instruction, with
cache parameters given in table 3-17.
There is no note about the reuse of value 0x49.

On page 26 of this manual (version 22), there is a "See also" section,
referencing the application note 485
 http://www.intel.com/support/processors/sb/cs-009861.htm

Unfortunately, I only can get an old version of this note (from 2003); and 0x49
is not used at all there.
What is the URL for the current version of application note 485?
