OK, well thanks for the warning.  Is that with -current, 2.0, or...?

I see that's with the mlx(4) driver -- do you think it's driver

(I've got the option of siop(4) or ahc(4) for the boot drives on this
system, though of course I'm stuck with isp(4) for the RAID)

I'd like to get KGDB working for this system -- it would make my current
pmap_bootstrap() debugging a lot easier too!
