Would you mind trying the nightly LCdproc tarball available on 
http://lcdproc.sourceforge.net/nightly/lcdproc-CVS-current.tar.gz ?
There have been a few changes since 0.5.1.

Don't worry, you do not need to install it. It can be run from the 
source directory. All you need to do is calling the freshly compiled
LCDd to an approriately adapted LCDd.conf:
Usually all you need to do after compiling LCDd and changing LCDd.conf
is:
	./server/LCDd -c ./LCDd.conf -f -r5 -s0 

The -s0 and -r5 make LCDd log alot more than a lot info to stderr.

Playing with brightness and contrast might also help.

Regards 
Peter
