Subject:   nvidia drivers hate me
Message-ID:  <20021206024746.F667-100000@master.gorean.org>

The native nvidia drivers work great in RELENG_4 with my geforce 4 mmx,
but in -current they hate me. I just upgraded to the latest -current and
I'm using XFree compiled on -current, no joy. It's always the same error:

panic: bremfree: bp 0xc7751bb8 not locked

I've tried both with and without agp. I have:

    Option      "NvAgp"         "3"

And I've tried with and without edid. Here is the trace:
