nvidia-kernel unresolved symbol

I'm having this weird problem:
when I "depmod -ae nvidia", I get

depmod: *** Unresolved symbols in /lib/modules/2.4.26-gentoo-r3/video/nvidia.o
depmod: __generic_copy_from_user
depmod: __udelay
depmod: boot_cpu_data
depmod: strncpy_from_user
depmod: iounmap
depmod: change_page_attr
depmod: __ioremap
depmod: irq_stat
depmod: __const_udelay
depmod: __generic_copy_to_user

same thing if I try to load it with modprobe.

I compiled linux (make menuconfig && make dep bzImage modules modules_install && cp arch/i386/boot/bzImage /boot/linux-2.4.26 && lilo) a bunch of times and tried with 2.4.25-gentoo-r2.

I also compiled nvidia-kernel from the ebuild and from nvidia package.
/usr/src/linux->linux-2.4.26-gentoo-r3/
I also have zlib{inflate|deflate} compiled as modules and they do load.

And I have those lines in my System.map:

c0426940 T __generic_copy_from_user
c0426850 T __udelay
c0100b20 D boot_cpu_data
c04269f0 T strncpy_from_user
c01ca810 T iounmap
c01cabf0 T change_page_attr
c01ca6e0 T __ioremap
c0160980 B irq_stat
c04268b0 T __const_udelay
c04268e0 T __generic_copy_to_user

"depmod -F /usr/src/linux/System.map -ae" works well but that does not help loading the module.

Any idea?
Thanks.

Did you also recompile nvidia-glx?

Yes I did, but nvidia-glx is a xfree module and nvidia-kernel is a kernel module I should'nt have any problem loading the module even if I dont update the glx module.

The problem is gcc-3.3.2-r5. I tried compiling the nvidia-kernel with gcc-3.2.2 from an old installation and it did work. !!! I'll now fill a bug report.
