>Description:
	
ncr and sym drivers cannot drive 53c810 chip on a machine with more than
256MB of memory
>How-To-Repeat:
	
Attempt to run NCR SCSI controller with 53c810 chip with either ncr or
sym driver and more than 256MB of memory
>Fix:

	
Work around by setting MAXMEM to 256*1024

Do we need to revive bounce buffers?
