I just tried your (gwk's) diff on my amd64. It's not 100% clear to me
what difference I should see, but the kernel boots and the machine
seems to run fine.

The included dmesg is from a kernel with sources dated ~19 feb, ubt(4)
enabled and a patch some developer sent me (hence the register dump on
the eephy).

Cheers,

Paul 'WEiRD' de Weerd
