Okay, I have a quick test. I think that the ptr that is screwed
is dc->dc_ramdac_intr. So, in this patch I don't reset it to
NULL after successfully completing the interrupt. Hopefully this
will show the problem. If not, then tga_intr may be being passed
a NULL -- but I would imagine that in that case you'd crash well
before you have a chance to run XalphaNetBSD.

Oh, one thing, so this is an intermittant failure? Or is this a different
card that you are running X on with a bit more success?
