[EDIT] sort it out, look at file /etc/OpenCL/vendors/nvidia.icd

In 302.17-1 its content is:
libcuda.so
which is also in the package.

But in 304.32-1:
libnvidia-opencl.so.1
which does not exists.

It turns out the file libnvidia-opencl.so.1 is new, so I added
install -D -m755 "libnvidia-opencl.so.${pkgver}" "${pkgdir}/usr/lib/libnvidia-opencl.so.${pkgver}"
to package_opencl-nvidia() in the PKGBUILD

Now it works like normal (tested with cgminer)

i believe libcl needs an update. please try to update it by change the nvidia version inside libcl PKGBUILD and let me know if is working.
Comment by Gašper Ažman (atomicity) - Monday, 13 August 2012, 19:17 GMT
I will. Currently, I'm running libcl 1.1-2, and the cl hello world works with nvidia drivers already. Will update and tell you.
Comment by Gašper Ažman (atomicity) - Monday, 13 August 2012, 19:24 GMT
Yeah, it works. I changed:
_pkgver=304.32
md5sums=('e6d9d1f73196d5f7ea110fef59bd466e') # on line 24
It installed and the hello world runs.
