Found, I guess?

Even though this was listed as "found" it didn't look like the manga was readily available. I had a download on my hard drive from circa 2009, most likely downloaded from the aforementioned HaruhiSuzumiya.net. I've added a Mega download link above.

I didn't want to edit the article since I can't recall the details for sure, but I remember reading that a large part of why this manga was cancelled was because the artist, Mizuno Makoto, had made arrangements with a hentai publisher to draw adult manga of the Haruhi characters. I can't precisely remember where I read that, however.
