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.
