Well, the problem with the black screen stays. If I remove fglrx, the 
gdm restarts perfectly. But with fglrx, after rebooting, dmesg gives:

Fire GL built-in AGP-support
Based on agpgart interface v0.99 (c) Jeff Hartmann
agpgart: Maximum main memory to use for agp memory: 439M
agpgart: Detected an Intel 855PM Chipset, no integrated grapics found.

[fglrx] total AGP = 65536

After /etc/init.d/gdm stop, it says:

(yes, MTRR option IS compiled in the kernel)

After /etc/init.d/gdm start :

   Any idea what can be the problem?
