What's the timeline for non-MPSAFE network drivers to be taken out
behind the woodshed?  Right now the list appears to be:

	an, awi, cm, cnw, cs, en, ex, fatm, ie, lnc, patm, fea, fpa,
	mn, ray, sbni, sbsh, snc, tx, wl, xe, ar, sr, plip

Of those, an, awi, cnw, cs, ex, ray, snc, and xe have PC Card
attachments, so I may wind up doing at least some of them (snc is pc98
only, cnw and ray are very obsolete wireless cards, so I don't think
I'll do them).
