That doesn't answer the second question.

I really have a hard time believing that all of 'auto.WP', '1303_02',
'patch', '0.1.54.1' and '0x36' are all significant.  No-one else seems
to need more than 4 components in a version number; what's so special
about this firmware?

And another question: can an outside observer compare version strings
and get any sense of which is newer?  Are the components in the right
order (most significant first)?

Ben.
