Brutally expensive, but worth it if you need top-notch quality. I got some of their soft shell pants in a tall size (6'6", 34" inseam).
I haven't seen much tall stuff from Patagonia recently, but also haven't been looking specifically for new pants.
I did also see that Cabelas sells a bunch of big/tall stuff, as Lars mentioned above. And I got some REI house-brand base layers for this season, so they may have something as well.
