I searched around and didn't see any mention of this anywhere, so I thought I'd ask. Has anyone used the MIT Tiny cores from http://hlt.media.mit.edu/?p=1695 , burned the 8Mhz Internal Oscillator bootloader (i.e. set the fuse bits) and then had it still run at 1Mhz? I was totally baffled by debugging…

ATTiny85 and MIT core not running at 8Mhz?
