System: NetBSD lorien 1.5_BETA2 NetBSD 1.5_BETA2 (LORIEN) #6: Sun Nov 26 13:29:19 GMT 2000 mark@lorien:/usr/src/sys/arch/i386/compile/LORIEN i386

	The 1.5 BETA 2 ESS 1868 driver (isapnp) fails to initialise
	correctly on i386, with error:
		ess: can't map SCR access registers
		ess0: essmatch failed
	I gather the SCR (system control register) stuff is pretty
	specific to the arm32/Shark architecture, and just fails to work
	on i386.
	Should be repeatable by anybody with a isapnp ESS 1868 card and
	the default 1.5 kernel
	Remove the calls to ess_config_addr() - which I gather is
	arm32/Shark specific - from sys/dev/isa/ess.c [there is in fact
	just one call to it, in essmatch() around line 810].
