I am pretty sure that ptxdist is dooing the right thing and the kernel config is up
to date but will use the other config for further reports.

No, the report before was for CONFIG_PREEMPT_LL. I know this is a little
weird to use a preempt rt kernel without enabling the preempt rt. But it also
improves latency.

If i understand you correctly you want a vanilla 3.0.1-rt8 bugsplat running on a pcm043?
(Attached to this mail the .config from ${PROJECT_DIR}/${PLATFORMNAME}/build/linux-3.0.1/.config)
Here we go 3.0.1-rt8 with CONFIG_PREEMPT_RTB=y:
