Well, I'm in the same camp. Mine is doing everything described.
I had modded mine back in about 2003-4 or there about. I broke it (screwed up XBMC) and never fixed it. Other than as a DVD player it hasn't been doing much in the last 5 or so years. Anyway, about 4 weeks ago I took the time to fix everything with EvoX and XBMC and have put this thing through some real punishment over the last 4 weeks. Season after season of TV, 40+ hours of movies, etc.
And today, after I transferred 20GB to it, I turned it back on for the tv and it was "On-off-On-of, red orange green." All LEDs on the chip are lit, I opened it up and am messing with it.
One time it hit the Xenium bios and it didn't note the fact that I had 2 dashboards installed (EvoX and Default). When I hit launch it was blank (as in no choices).
I'll post back if I find something out, if not, I gotta get a new chip as my grad school loan checks won't allow an upgraded system of any sort.
