: Warner was worried about breaking support for

: if you, Julian, have such card for testing, then there is
: not a problem of testing and fixing trivial bugs.

During my usual testing regiment, I test about 20 different flavors of
NE-2000 base PC Cards.  I believe that my PC Card testing is clost to
exhaustive in terms of flavors of card that are supported.  I also
test two or three ISA cards if time and circumstances permit.  The ed
driver supports many other ISA cards than I have access to.  I also
try to test PCI cards, but I have to test that on a SBC at work which
I have limited access to.  I have a bunch of CBUS cards, but my pc98
machine is having issues[*] at the moment, otherwise I'd try to test
them as well...

Of course, I don't run the whole gammet of cards for each change.
Just retrieving the cards from my card storage; plugging them in;
doing minimal testing; and then putting them back in storage for my PC
Card collection takes between 2 and 3 hours (between 5 and 10 minutes
per card once all is said and done).
