Yes it is, however the values I get for the symbols in all 3 cases seems
to be the same:

dg@major:~$ readelf -s /lib/modules/2.6.33-rc2-major/build/vmlinux|grep " _text"|head -1
49775: ffffffff81000000 0 NOTYPE GLOBAL DEFAULT 1 _text
dg@major:~$ grep _text /lib/modules/2.6.33-rc2-major/build/System.map |head -1
ffffffff81000000 T _text
dg@major:~$ grep _text /proc/kallsyms |head -2
ffffffff81000000 T _text
ffffffff81023840 T set_kernel_text_ro

Do you think that it could still be the cause?
