	Me organized?? Ha! 
>Release:        -current as of Apr. 19th
>Environment:

System: NetBSD rafal.slip.uiuc.edu 0.9a RAFAL#0 i386
	wt driver configured in kernel
	Everex QIC-02 controller 
	Current kernel as of 4/19

>Description:
	the wt driver was never fully updated to the new standard for
	probe and attach routines, it still returns the # of ports from
	probe, instead of sticking it in the proper struct...

>How-To-Repeat:
	1. build kernel with wt in it...
	2. let wt probe your controller...
	3. watch the kernel tell you "wt0 at isa0 0x280-0x87c" or something
	   else absurd.
