Everybody new to driver development - RTFM - Read Rubini's book.
Most people having problem with hello_world driver don't understand that you should have Linux kernel sources installed and configured, 'make menuconfig' is your friend. Only after that you can start building your own drivers.
Good place to put sources into is for example /usr/src/linux-2.6.12 (for kernel 2.6.12). If you untar kernel souce into /usr/src you would be pretty close to that.
Then make sure you have following among gcc flags in your Makefile:
If you do not have that, #includes like <linux/types.h> would get file /usr/include/linux/types.h, which is certainly not what you want to be included as opposed to /usr/src/linux-2.6.12/include/linux/types.h
