Sounds like the user defined character set gets tromped on even if bignum
support is missing. I'll change the patch to make the bignum widget
initialisation dependant on the lcd_bigclock boolean.

I'm not sure if having changed the bigclock setting bool causes the
lcdserver to re-init itself. By any chance does restarting the server with
the bool off allow the existing (non-bigclock) stuff to run OK?

BTW - on my HD47780 display, I had to integrate the new adv_bignum.c stuff
into the driver to get a 2 line bignum display (the existing stuff in
0.5.0 is for 4 line displays only). Works really well! I've got the patch
here is you're interested or you'll find it on the lcdproc list.
