Safe to upgrade to current kernel?

Hello I have just installed Ubuntu a few days ago, runs nice, I love it. I am somewhat familiar with compiling kernels from my experiences with slackware.

I have got most of my peripherals to work except for my Wacom UD-1218. When i did make for the driver it said:

Drivers not enabled as modules in your kernel config but requested through configure are NOT built
So I am assuming that I need to compile a new kernel.

Now my question is this:

What is the process for compiling a kernel in Ubuntu, is it?:

make menuconfig
make modules_install

Now normally I use lilo, but since Ubuntu comes with grub thats what I am using, what are the commands for grub to add the new bzImage?

One more question, Is is possible to use the config im using now for the newest kernel?

example, use .config from Ubuntus 2.6.17-11 kernel source and apply that to the newest kernel I will be downloading (2.6.20).

It should be like on debian, so have a look here:
grub will be updated by /usr/sbin/update-grub automagically if you have postinst_hook set to /usr/sbin/upgrade-grub in /etc/kernel-img.conf

One more question, Is is possible to use the config im using now for the newest kernel?
When you unpack your kernel, before doing make, do
make oldconfig, it will prompt you for the new options, the already configured one will be taken from your running kernel.
If you directly type make (or make-kpkg) in a new kernel tree, it sets the new options to their default values.

Kernel compilation depends on the kernel version, not much on the distribution used (unless you install using binary tools, but that's not compilation then). All needed instructions are found in the documentation (README and INSTALL files) that is distributed with the kernel source code.

ok, sounds good, one more question before I proceed.

When I used slackware I was using the latest NVIDIA driver from their website, i have GeForce fx5500 video card, I haven't been able to successfully install that one (Ubuntu), so I have been using the nvidia driver that shows up in synaptic.

I remember every time I recompiled the kernel I would have to reinstall that NVIDIA video driver, so, Should I un-install my current NVIDIA driver I used with the download manager?

Also, is there any difference in the NVIDIA driver from Synaptic and the one provided on the NVIDIA website? I would rather use the one on their website but I am scared that I will ruin X again like I did the first time I tried to install it on Ubuntu. The nvidia driver provided on their website will not install while X is running, and the only way I know of getting to a prompt in Ubuntu is to start in recovery mode. The last time I did that I ended up reinstalling Ubuntu.

Any info is appreciated. Thanks
