long append="..." causes yaboot to reject entire yaboot.conf (MAX_TOKEN too small)
yaboot's second/cfg.c has:
#define MAX_TOKEN 200
When yaboot parses its config file, if it encounters a quoted string (like
append="...") longer than MAX_TOKEN, it rejects the entire config.
Typical preupgrade usage uses ~250 chars, which means preupgrade currently
renders ppc systems unbootable without this patch.
Suggest increasing MAX_TOKEN to.. let's say 511. cfg.c does "char
buf[MAX_TOKEN+1]", and everyone loves powers of 2.
