I guess you mean the linux kernel version is 2.0.33.
Which version of the SuSE distribution are you using ?
What does your login prompt say ?
It should be something like "Welcome to SuSE Linux <suseversion> - Kernel
<kernelversion>"

BTW all pcmcia related kernel modules belong to the pcmcia package.
You may have to install the pcmcia source package from the zq series with
YaST.
If you do that you will have the file pcmcia-cs-<some version
number>.tar.gz in your /usr/src/packages/SOURCES directory.
Recompile that package. (unpack using tar xvzf, ./configure, make all,
make install)

I think you downloaded modutils not modules.
Most kernel modules are part of the kernel sources (except for example the
pcmcia modules which are part of the pcmcia package).
So you would have to install the kernel sources from your SuSE CD's or
grab some newer kernel from ftp://ftp.kernel.org/pub/linux/kernel/v2.0/ or
ftp://ftp.kernel.org/pub/linux/kernel/v2.2/.
Newest 2.0 kernel is 2.0.38.
Newest 2.2 kernel is 2.2.18.
You most certainly don't want to try out the 2.4 kernel and
even more you don't want to try a kernel with an odd second version number
because those are developer kernels which tend to be very unstable
sometimes and may corrupt your filesystem, things like that (2.1.x,
2.3.x, 2.4.x-pre )

But my guess is you will only need the pcmcia package and recompile that
which should be _alot easier_ than recompiling your kernel.

Hope that helps,
