It seems that the acces point is found but that association doesn't succeed. I had that I use TKIP as encryption method. I just wanted to know if this is a known bug of the driver or of wpasupplicant and we may hpe that it will be solved when the final release of the 2.6.13 will be released.

OK.  I am not really good in programming and since I have other problems 
with kernel 2.6.13 (for example with software suspend),I will wait for 
the final release.  I guess that the problem with WPA support in the 
driver will be solved by that time but since we can also use -Dwext as 
parameter for wpasupplicant, maybe it is not a real problem.
