I upgraded to gcc-3.3.6 today and when recompiling the drivers (kernel
modules in the portage tree) I got some warnings and the modules fails
to load:

So I guess there is something wrong with my gcc upgrade. I guess I need
to do a proper toolchain upgrade?
I have already compiled those (in specified order):
gcc (3.3.5 -> 3.3.6) uclibc binutils
But it still fails to find the SSP symbols.
What can I do to fix it? Do I have to recompile the world? (like
described in http://www.gentoo.org/doc/en/new-upgrade-to-gentoo-1.4.xml)
Are there any shortcuts?

no, your module build process (Makefiles) does not add -D__KERNEL__ to the
build, so ssp will be enabled on the built modules (not supported by any
gentoo kernel).
Nothing in the kernel and module build process is allowed to enable
-fstack-protector (either by CFLAGS or any other method)
Rebuild one of the above modules and paste your compiler line.

I worked around it by selecting the nossp gcc profile, compiled all the
modules and switched back to the standard hardened gcc profile. Now I
cannot reproduce it.
Could it have been a bug in portage that have been fixed? (I did a
emerge -ssync today to get that gdbm update)
Thanks!

I don't think so, as I said, the way you compiled your modules was
incorrect. if gcc gets -D__KERNEL__ no ssp is enabled (independently of
the chosen hardened/non-hardened compiler), if you build within the normal
kernel tree, this is set for you, but if you try to build addons, this has
to be done by the Makefile used.
That's why I asked for your command-line for one of these modules (to
clarify this) ... it seems too late.
