Modem Howto
Today I investigate to find a way to have my modem working under linux...
After running the tool Linmodem, It look like the modem in my Inspiron 1501 is supported by the driver HSFMODEM from Linuxiant.
I install the free version (limited to 14.4k) and afer a reboot, I start minicom on /dev/modem and this is what I got:
AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0
OK
ATI3
hsfmodem-7.60.00.01x86_64full
OK

ATI linux driver kernel 2.6.20
I found the following information on how to fix the ATI linux driver for kernel 2.6.20:
Kernel 2.6.20 + FGLRX 8.33.6 = not compiling
Here is what I did:
I downloaded and installed newest ati drivers (ati-driver-installer-8.33.3-x86_64.run)
After installation, I just downloaded the patch and (as a root):
cd /lib/modules/fglrx/build_mod
patch -p6 < {path to patch}/fglrx-2.6.20.patch
./make.sh
cd ..
./make_install.sh
And then restart X (of course you might to need to modify your xorg.conf if you are doing new install of ati fglrx drivers).
Hi follow these steps and fix the problem for me...

ACPI configuration - Lid event
I decide to play a little bit with the ACPI configuration. For now, each time I close the lip of my laptop, the system automatically lock the screen.
Now that the suspend is working since I update my kernel to 2.6.20, I want to customize the lip action a little bit. I want to check if the system is on the AC adapter, if it's, locking the screen is the good action. But if the system is running on the battery, I want it to turn on the standby mode when the lid is close.
First, the ACPI scripts are located in the /etc/acpi directory, and the configuration file for the lid event is /etc/acpi/lid.sh
To check the state of the AC adapter, we can do it with the following : cat /proc/acpi/ac_adapter/ACAD/state
If the AC adapter is present:
state: on-line
If we run on the battery:
state: off-line
To turn on the stanby mode, we can do it with the following command:
echo -n mem > /sys/power/state
To turn on the hibernate mode, we can do it with the following
echo -n disk > /sys/power/state
So based on that, this is my change:

Hibernate support with kernel 2.6.20
I read some post on the net explaining that with kernel version < 2.6.19 the hibernate and suspend may not work with the AHCI SATA. It may not work beause the AHCI was not restore after the suspend...
With the default Ubuntu 6.10 kernel (2.6.17-10), the suspend was not working.
So I upgrade to kernel 2.6.20:
This is the step:
cd /usr/src
sudo wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.20.tar.bz2
sudo tar xjf linux-2.6.20.tar.bz2
cd linux-2.6.20
cp /boot/config-2.6.17-10-generic .config
make oldconfig
make
make modules_install install
cd /boot/
mkinitramfs -o initrd.img-2.6.20 2.6.20
Then I add the following grub entry in /boot/grub/menu.lst:
title Ubuntu, kernel 2.6.20
root (hd0,4)
kernel /boot/vmlinuz-2.6.20 root=/dev/sda5 ro quiet pci=nomsi
initrd /boot/initrd.img-2.6.20
quiet
savedefault
boot
Note: With kernel 2.6.17-10, I was using the acpi=force irqpoll kernel option, but the system hang when I used it with 2.6.20, do I remove it.
Then the hibernate and suspend work like a charm...
Enjoy,
