Omg, perhaps you are right, i'm not sure, because this kernel was 
compiled by my friend and i said him to recompile the kernel because i 
changed the memory support and he said he has recompiled the kernel and 
restarted the machine.

uname -a:
Linux muranyi 2.6.11.12-grsec #1 Tue Jul 26 03:04:39 CEST 2005 i686 
GNU/Linux

ls -all /boot:
*lots of file*
-rw-r--r--   1 root root   29391 Aug  1 13:36 config-2.6.11.12-grsec
*lots of file*

The dates are not the same, does it mean it isn't the config of the 
running kernel? (Might my friend was bit a lazy?^^)

I dont have any shared RAM display card and it was working correctly 
with Kernel 2.4.27-grsec/2.4.31-grsec.
