Break out obscure ISA cards into their own files, as well as ne2000

Browse Source 
and wd80x3 support.  Make the obscure ISA cards optional, and add
those options to NOTES on i386 (note: the ifdef around the whole code
is for module building).  Tweak pc98 ed support to include wd80x3 too.
Add goo for alpha too.

The affected cards are the 3Com 3C503, HP LAN+ and SIC (whatever that
is).  I couldn't find any of these for sale on ebay, so they are
untested.  If you have one of these cards, and send it to me, I'll
ensure that you have no future problems with it...

Minor cleanups as well by using functions rather than cut and paste
code for some probing operations (where the function call overhead is
lost in the noise).

Remove use of kvtop, since they aren't required anymore.  This driver
needs to get its memory mapped act together, however, and use bus
space.  It doesn't right now.

This reduces the size of if_ed.ko from about 51k to 33k on my laptop.
