Interrupts: Sorry, I am not sure, what you are asking for. Yes the system has interrupts
but I suspect that is not the answer to your question.

ACPI: never used it

APM: I had the apm module in my /etc/modules but deleted it some days ago (because
I also thought that it might cause the trouble). There was no crash since then, but
it was just some days ago and sometimes it takes very long for the next crash.

DMA: I use dma for my HD. Or are you asking for video-dma? Is there such a thing as dma
to my video-card (AGP)?
