There are no chipsets (yet) that dispose of the LPC interface, and none that can't run a legacy parallel port on LPC (as part of a super I/O chip) either.
It's just that the /need/ for having such a port has been rapidly dwindling over the past couple of years, and that the LPT port is the number one space hog on the ATX panel. Sum these two facts up, and you know why it's (finally) disappearing in favor of more useful things like DVI, digital audio, more USB, etc. whatever.
