Whoops!  It looks like the df command isn't being built into busybox. 
If you want to add it, uncomment the line that says "//#define BB_DF" 
in src/router/busybox/Config.h and rebuild. 

I will probably enable this in CVS soon.   

The only filesystem you really need to worry about though is /tmp,
because it is a memfs.  the rest of the filesystems are readonly
squashfs anyway so don't worry about them filling up :)
Can you stat memory in general with "cat /proc/meminfo"

Yes, Keith Lofstrom is the man to talk to about that.

I know a number of people using the serial port hack and it seems to
work quite well.  I haven't seen the dual port hack in action but I've
heard success reports in. the various forums.

I'm assuming you've tried out the WRT54G kismet drone?   You should talk
to Sam Churchill at PTP this week, we may be helping him out with his
wireless bike v2.
