Markus,
Ok, I finally got everything working. The interrupt issue was due to a bug in the perfmon code.
But I found another bug in ds.c.
The absolute maximum MUST be at buffer+size+1 but the threshold can be anywhere between the start of the buffer and buffer+size. You had it set past the end of the buffer (at +1), therefore PEBS was not generating any interrupts.
