Don't forget the screwy Alpha, with a 2-column machine-type header
at the top of the file. (would love to know why...)

Sadly, 'ps' must use both /proc/ksyms and the System.map file.
Even this isn't really enough, but it will have to do. We all
get to enjoy missing and/or misleading WCHAN data, with the
non-Debian users getting silent errors.
Suggestion: don't even try to parse these files unless you really
desperately need to get the data. The formats are NOT obvious,
and in fact are not even defined in a stable or portable manner.
