we have both, a beagle xM-B and a beagle xM-C. The following works on
both boards and is different from your patch. It is not possible to
differentiate between Rev xM-A and xM-B. Anyway, the only difference is
in the processors silicon revision (ES 1.0 to ES 1.1).

ok thanks, I'll include it with an update to the previous patch that fix a 
problem when loading the kernel with USB clocks enabled.
