I actually fixed this a couple days ago.  My fix is similar to yours.

I sent a similar patch to the list a while ago and just installed.
The difference with yours is that it only uses syntax-ppss if the major
mode sets a specific variable.  The reason for it is that in major modes
like tex-mode or perl-mode where the syntax-tables are not quite up to the
task, using syntax-ppss means that if the syntax functions get confused the
comment-related operations suddenly don't work at all any more.
