It is not only possible. It is already done.
It is in CVS HEAD but not yet in the stable branch
I wanted to have more testers before bringing it to stable.
You can download it from:

For a few drivers - CFontz633, CFontzPacket, HD44780, IOWarrior,
serialVFD - I updated the character definition functions to use only one bit
per pixed. instead of a whole byte.
I also updatd the ad_bignum library accordingly and updated the drivers
mentioned above to use the adv_bignum library.

So all these drivers currntly have the full adv_bignum support:
CFontz633, CFontzPacket, HD44780, IOWarrior, serialVFD
With more to come if someone is willing to convert the driver
and send patches or is willing to test.

Now that we have a configuration file for the lcdproc client
you can make the time configurable.

Please make your changes against CVS HEAD
