Update of newbus API broke system

My current system will no longer boot. cvsup today at about 17:30 UTC
and the new kernel crashes connecting the fdc during the boot
operation. Looks like the change to the newbus API broke it.

I will need to hook up a serial cable to get a good backtrace and such,
but here is the short for in hopes that it will help. Hand transcribed,
so errors are possible.

kernel trap 12 with interrupts disabled


Fatal trap 12: page fault while in kernel mode
fault virtual address	=0x0
fault code		= supervisor rad, page not present
instruction pointer	= 0x20:0x0
stack pointer		= 0x28:0xc0c20a50
frame pointer		= 0x28:0xc0c20a6c
code segment		= base 0x0, limit 0xfffff, type 0x1b
			= DPL 0, pres 1, def32 1, gran 1
processor eflags	= resume, IOPL = 0
current process		= 0 (swapper)
[thread pid 0 tid 0 ]
Stopped at:     0:      *** error reading from address 0 ***

The end of the backtrace is:
configure(0,c1ec00,c1e000,0,c0432e25,...) at configure+0x9
mi_startup() at mi_startup+0x96
begin() at begin+0x2c

System is a ThinkPad T43 with 2 GHz Pentium-M. the crash makes it cleat
that something has been stepped on. Did come bit of the commit get
missed?

Thanks,
