I haven't tested this myself, and it will be a time-consuming process,
but you can rebuild the realtime kernel with this driver included.
0. Because you're going to overwrite the installed kernel, install a
generic kernel so you can still boot even if something goes wrong
with the new kernel you're installing
sudo apt-get install linux-image-2.6.24-16-generic
(if you can live with rebooting between work on arduino and work on emc,
maybe it's sufficient to stop here -- the -generic kernel should have
the ftdi_sio driver available)
1. Prepare your system with packages needed to rebuild the kernel
sudo apt-get install build-essential fakeroot
sudo apt-get build-dep linux-image-2.6.24-16-rtai
2. Get the kernel source in a subdirectory of the current directory
wget
http://linuxcnc.org/hardy/dists/hardy/base/source/linux_2.6.24-16.30.linuxcnc.1.tar.gz
wget
http://linuxcnc.org/hardy/dists/hardy/base/source/linux_2.6.24-16.30.linuxcnc.1.dsc
3. Extract the kernel source
dpkg-src -x linux_2.6.24-16.30.linuxcnc.1.dsc
4. Change to the linux-2.6.24 directory and apply this patch with 'patch -p0':

6. Install the package

7. Reboot and test the new kernel (with two kernels you may need to
choose the rtai kernel at the boot menu)
8. If you're satisfied with the new kernel, you can remove the
linux-2.6.24 directory and the linux-image-2.6.24-16-generic package you
installed.
