Hi Alan,

I had a somewhat more comprehensive change in mind, which hopefully will
head off problems of this sort in the future. (E.g. when kdev_t becomes
a pointer to a table entry, as seems to be the design intent.)

I'm testing the patch now and will have it ready tomorrow. There may be
a shortage of 64-bit testers though; the alpha folks seem to be having
other problems.

Regards,
Bill
