I've been using this for the past few days to hack with SLIME on the device - it works very nicely - thanks! I was experimenting with building stand-alone executables (with EXT:SAVEINITMEM) but it seems that any image containing GTK locks up chewing CPU when you reload it (and I'm not familiar with Clisp and don't have gdb on my phone so I'm not sure how to get more details about what it's doing). Am I doing something stupid or is that the kind of stability problems you're talking about?

It's a great hack anyway, bravo! I look forward to apt-getting it one day.
