isa_device.h: Added flag for sensitive HW. ed# seems to break if anything

Browse Source 
else has been probed.  This feature could go away again, if we can curb the
problem another way.

if_ed.c, syscons.c:  Set the above flag.  ed# because it needs it, syscons
because it looks stupid to "detect" the display you have already filled up
with text :-)

bt742a.c: Check bt_cmd() return-val during probe, thus failing on adaptec's.
Also silenced various printf's during the probe.

isa.c:  Probe devices with the above flag set before the rest.  Reduce the
number of "conflict" messages per device to one.

***
Please test the GENERIC-kernel now, if nobody can make it fail, GENERICAH
and GENERICBT has a finite and short life-expectancy...
