Change 37195 by marcel at marcel_nfs on 2003/08/29 14:44:17

	Even though we have a 4-byte wide memory I/O resource,
	accessable registers of the z8530 have offsets:
		Channel B control	0
		Channel B data		2
		Channel A control	4
		Channel A data		6
	
	We're accessing bus space outside our assigned range.
	For now, give each port 4 bytes of bus space even though
	it's technically speaking invalid. Something is going on
	with sbus and I don't know yet what it is...
