Hi colleagues,

I got some time today to redo the tests on arm system, here are some
updates.

I did make a small mistake at testing yesterday, as I took a wrong 
toolchain, which doesn't even support NPTL to compile the kernel 
and rootfs for the testboard. Today I recompiled the whole bsp with 
a nptl enabled toolchain with eabi. (gcc 4.1.1, glibc 2.4.90). Test 
results both in Kernelspace and userspace stay, however, quite the 
same. The clock APIs still appear not to work properly.

This stays the reproducable. I'd try to examine it more exactly later.

Further I found a minor bug, which causes Compilationerror while
compiling for pxa. I attached the patch with this mail.
