Thanks.  I just tested on my laptop and it doesn't keep over reboot indeed.
 My error was I just installed a new machine where DMA was off on boot and
I used -k1 -d1 and that fixed it.  Well, that I built a new kernel about
that time might have made the difference too!

moseley@laptop:~$ fgrep DMA /boot/config-2.4.18-xfs-laptop 

is what I see in my laptop config.

Thanks for the correction!
