I don't recall the exact version I was booted to at the time, but on the next 
bootup I only had 2 kernels left as choice, whereas smart had been told to 
leave the kernels alone, yumex apparently had been given no such 
instructions, so it merrily nuked the one that was running, /lib/module 
entries and all.

Smart didn't have any livna repos defined, and wouldn't handle some sort of an 
mplayer update because of that, so I used yumex.  Now smart is crashing too.

No, its init was part of my rc.local.

I had it set in the kde prefs for 2 hours.

Its generally a quick glance to get the speed, which roadnav displays along 
the bottom of the screen in a font I can read in about 1 second flat.  
Anything else I generally have to pull over to do because the mouse pointer 
is so damned tiny, and my bluetooth mouse doesn't run at less than 500 mph.  
The whole screen is about a 1.5x2.5" area on the pad, and thats with the 
mouse speed set at 1.  A heads up display would be nice, but there is way too 
much detail on the roadnav screen for anything smaller than a 22" monitor, so 
the speed reading is about all that is usefull when in motion.  And it bugs 
me that you can't set north to up, it redraws the map so the direction your 
moving is up, totally scrambling the view IMO.  But that's another bitch that 
may get fixed by recompiling it from src after a few tweaks.  This was my 
first foray into using it on the road, and the author hasn't answered the 
email I sent so I guess its officially abandoned.  Oh, and don't ask it for 
directions, which it does a nice job of, but it never gives back the cpu and 
you have to quit it and reboot to recover.  That may take 10 minutes just to 
quit, but the machine is still stuck at 100%.
