I tried to apply your "patch", it worked, but it does not compile. I'm 
afraid there's a problem with the i2c.h include.

That's what I get when I do a make:

gcc -DHAVE_CONFIG_H -I. -I. -I.    -I/usr/X11R6/include -D_GNU_SOURCE 
-Wall -W -g -O2 -c drv_HD44780.c
In file included from /usr/include/linux/sched.h:12,
                  from /usr/include/linux/module.h:10,
                  from /usr/include/linux/i2c.h:31,
                  from drv_HD44780.c:216:
/usr/include/linux/jiffies.h:16: error: parse error before "jiffies_64"

                  from /usr/include/linux/i2c.h:31,
                  from drv_HD44780.c:216:
/usr/include/linux/bitmap.h: In function `bitmap_empty':
/usr/include/linux/bitmap.h:15: error: `BITS_PER_LONG' undeclared (first 
use in this function)
/usr/include/linux/bitmap.h:15: error: (Each undeclared identifier is 
reported only once
/usr/include/linux/bitmap.h:15: error: for each function it appears in.)

and so on...

The first error is a missing "u64" declaration, which is defined in 
asm/types.h, but only if the symbol __KERNEL__ is defined (which is not 
in a userspace program)

I commented out all failing sections in the driver with a #if 0, and 
checked in the driver. Maybe you want to have a look at it, and find out 
how to make it compile cleanly.

bye, Michael
