I've got OpenBSD on a Mini10 as well (love it) but the graphics are slow on the GMA500 chip (no Polsulbo driver so it falls back to using VESA).  Does yours have the same chipset and did you find accelerated drivers for it? Or do you just use it at the console (where it's pretty snappy).

I've upgraded mine to the maximum 2GB of RAM. put a newer SSD in it, and replaced the BCM wireless card (which never worked reliably) with an Atheros.  But it's a wonderful little unit.

Thanks for the episode!
