Thank you for your help. Here's my dmesg log:

Serial: 8250/16550 driver $Revision: 1.1.1.1 $ 4 ports, IRQ sharing disabled    
serial8250: ttyS0 at MMIO 0x11e003f8 (irq = 40) is a 16550A

and:

:~# more /proc/tty/driver/serial

1: uart:unknown port:00000000 irq:0                                             
2: uart:unknown port:00000000 irq:0                                             
3: uart:unknown port:00000000 irq:0 

Right now I can connect to the modem using minicom. I changed the band to 850 
Mhz (my internet provider's band) and enabled all functionality of the device. 
After that I created a new connection with pppconfig but when I select to find 
the modem automatically, it complains about not finding one. 

Then I select /dev/ttyS0 manually, here's my config:

Number   *99#                 Telephone number
User     kolbi3g              ISP user name
Password kolbi3g              ISP password
Speed    115200               Port speed
Com      /dev/ttyS0           Modem com port
Method   PAP                  Authentication method

Modeminit    ATZ                  Modem init string             
ISPConnect   \d\c                 Connect response                     
Pre-Login                         Pre-login chat     
Defaultroute defaultroute         Default route state

 disabled             Turn persist on or off     Nameservers  static            
   Change DNS
Add-User                          Add a ppp user   
Remotename   kolbi3g              Change remotename
Idle-timeout none                 Idle timeout

These parameters were taken from a wvdial config file that I use to connect 
through a Huawei USB 3G module and work fine, so I don't really know what is 
going on...

I'm thinking about going back to kernel 2.4 and check that I'm doing everything 
correctly.
