Justin T. Gibbs 7357f64514 Classify all EISA cards with major firmware revions '2' as 742As. 
This allows us to successfully attach early Storage Dimension cards.

Allocate mailboxes for the 742A bellow the 16MB limit.  Although these
cards seem to be able to deal with all other types of data anywhere
in a 32bit address space, 24bit addresses are required for mailboxes.

bt_eisa.c:
	Add device IDs for all Storage Dimension products I could
	find from their web site.

Thanks to Ted Mittelstaed for loaning me the equipment to diagnose
and fix these problems.
